How many moles are in pbcl2?

The number of moles in PbCl2 can be determined if the mass of the substance is known, using the formula: moles = mass/molar mass.

For those who require additional information

PbCl2 is the chemical formula for lead (II) chloride, a salt of lead and chlorine. It is a white solid with a melting point of 501°C and is insoluble in water. The number of moles in PbCl2 can be calculated using its molar mass, which is the sum of the atomic masses of lead and chlorine.

Lead (II) chloride has various industrial applications, including as a component in PVC stabilizers, as a pigment in ceramics, and as a reagent in chemical synthesis. However, it is also toxic and poses health risks to humans and the environment.

As for a quote on the topic, Marie Curie, the Nobel Prize-winning physicist and chemist, said, “Nothing in life is to be feared, it is only to be understood. Now is the time to understand more so that we may fear less.”

To calculate the number of moles in PbCl2, we can use the formula:

moles = mass/molar mass

The molar mass of PbCl2 is 278.1 g/mol. Therefore, if we have 278.1 g of PbCl2, we will have one mole of it. Similarly, if we have 139.05 g of PbCl2, we will have 0.5 moles of it.

To make this easier, we can use a table to compare the mass and moles of different amounts of PbCl2:

139.05 0.5
55.62 0.2
27.81 0.1

In conclusion, knowing the molar mass of PbCl2 allows us to calculate the number of moles in a given mass of the substance. While PbCl2 has industrial uses, it is important to be aware of its toxic properties and take measures to avoid exposure.

Video answer

The video teaches how to calculate the molar mass of Lead (II) Chloride, also known as PbCl2. To find the molar mass, you add the molar mass of lead to twice the molar mass of chlorine since there are two chloride ions in the compound. The resulting molar mass is 278.1 g/mol. Keep in mind that the value may slightly differ depending on the number of decimal places in the periodic table used.

Many additional responses to your query

(PbCl2) has a molar mass of 278.1 g/mol.


The answer is 278.106. We assume you are converting between grams PbCl2 and mole. You can view more details on each measurement unit: molecular weight of PbCl2 or mol This compound is also known as Lead (II) Chloride. The SI base unit for amount of substance is the mole. 1 grams PbCl2 is equal to 0.0035957512603108 mole.

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles PbCl2, or 278.106 grams.

There are 0.0291 moles of PbCl2 will be formed.

Step 1

First of all, we need to write the balance equation of the reaction

PbO + 2HCl. ————–%3E PbCl2 + H2O

Step 2

Now, All we need to find out it’s mole.


PbO – 6.5 gm

HCl – 3.2 gm

Note :- M.mass of Pb is 207.2 u

Mole = Weight of PbO/ M.mass of PbO

= 6.5/223.2

= 0.0291 mole

Step 3

In balance reaction, We take 1 mole of PbO to yield 1 mole of PbCl2.

So, Mole of PbCl2 = 0.0291 ×1/1

= 0.0291 moles

Beside above, Is PbCl 2 soluble in water?
PbCl 2 is sparingly soluble in water, solubility product Ksp = 1.7 × 10−5 at 20 °C. It is one of only 5 commonly water-insoluble chlorides, the other 4 being thallium (I) chloride, silver chloride (AgCl) with Ksp = 1.8 × 10−10, copper (I) chloride (CuCl) with Ksp = 1.72 × 10−7 and mercury (I) chloride (Hg 2 Cl 2) with Ksp = 1.3 × 10−18.

Also Know, Where does lead ion occur in solid PbCl 2?
Answer to this: It also occurs naturally in the form of the mineral cotunnite . In solid PbCl 2, each lead ion is coordinated by nine chloride ions in a tricapped triangular prism formation — six lie at the vertices of a triangular prism and three lie beyond the centers of each rectangular prism face.

How much chlorine is in a mole of lead (II) chloride?
So, every mole of lead (II) chloride will contain 70.906 g of chlorine and 207.2 g of lead. This is equivalent to saying that every 100 g of lead (II) chloride will contain 25.496 g of chlorine in the form of chloride anions and 74.504 g of lead in the form of lead (II) cations.

Keeping this in view, What is the percent composition of PbCl2 in g mol?
Calculations: Formula: PbCl2 Molar Mass: 278.106 g/mol 1g=3.59575126031082E-03 mol Percent composition (by mass): Element Count Atom Mass %(by mass) Pb 1 207.2 74.5% Cl 2 35.453 25.5%.

Hereof, What is PbCl 2?
PbCl 2 is an intermediate in refining bismuth (Bi) ore. The ore containing Bi, Pb, and Zn is first treated with molten caustic soda to remove traces of arsenic and tellurium. This is followed by the Parkes process to remove any silver and gold present.

How much PbCl2 dissolves in 100 g of water? Nothing will change since only 0.22 g of that 100 g will be the total amount that will dissolve, regardless of how much solute is added. Molar solubility will still remain the same as well as our solubility product constant Ksp. A chemist adds 10.00 g of PbCl2 to 50.00 mL of water at 25°C and finds that only 0.22 g of the solid goes into solution.

Is PbCl2 a saturated solution?
Since we have PbCl2 precipitate, we know that this is a saturated solution of Pb (2+) and Cl-. Out of the 10 grams of PbCl2 added, only 0.22 grams gets dissolved into solution.
