# Immediate reaction to – how many grams are there in 4 50 moles of Ba NO2 2?

Contents

There are 485.386 grams in 4.50 moles of Ba(NO2)2.

## So let’s look at the request more closely

According to the given question, there are 4.50 moles of Barium Nitrite (Ba(NO2)2) and we have to determine its weight in grams. To calculate the answer, we need to use the formula:

Weight = Number of Moles x Molar Mass

The molar mass of Ba(NO2)2 is (137.327 + 28.01352) g/mol = 205.34 g/mol. So, the weight of 4.50 moles of Ba(NO2)2 will be:

Weight = 4.50 moles x 205.34 g/mol = 924.03 g or 485.386 g for correct significant figures.

As per John Lubbock’s quote, “What we see depends mainly on what we look for.” Likewise, understanding chemical compounds and their mass compositions is a fundamental aspect of chemistry. Here are some interesting facts on the topic of molecular weights that might enhance your understanding:

• Molecular weight (MW) is a physical property commonly used in chemistry to determine the mass of a particular molecule.
• Molecular weight is also referred to as molecular mass, formula mass, or molecular weight average.
• The molecular weight is expressed in grams per mole (g/mol).
• Using the molecular weight, we can calculate the number of moles in a given mass of a substance, or the mass of a substance in a given number of moles.
• The molecular weight of a compound can be calculated by adding the atomic weights of all the atoms present in the compound.
• Atomic weights are found on the periodic table and are expressed in atomic mass units (amu).
• The atomic weights of most elements are not whole numbers because they represent the average weight of all the isotopes of that element present in nature.
• The molecular weight of a compound is useful in many chemical applications, such as determining the correct amount of reactants to use in a chemical reaction or calculating the concentration of a solution.
• There are various online molecular weight calculators available that can easily determine the molecular weight of any compound provided the chemical formula.

Here is a table showing the molecular weights of some common chemical compounds:

Chemical Compound Molecular Weight (g/mol)
Water (H2O) 18.015
Sodium Chloride (NaCl) 58.443
Glucose (C6H12O6) 180.156
Methane (CH4) 16.043
Ethanol (C2H5OH) 46.07

In conclusion, understanding molecular weights is crucial to grasp various concepts of chemistry. With the help of formulae and calculators, we can easily calculate the molecular weight of any substance.

The video explains how to convert moles of a substance to grams using the molar mass. The molar mass is obtained by adding the masses of all elements from the periodic table. To convert moles to grams, multiply the moles by the molar mass, and to convert grams to moles, divide the grams by the molar mass. Units must be canceled out to achieve the correct result.

## On the Internet, there are additional viewpoints

Therefore, there are 1031.85 grams in 4.50 moles of Ba(NO2)2 .

number of moles (n) = 4.50 moles

mass (m) = n×M [This is what you are trying to find]

molar mass (M) = ?

Your first step is to find out what is the molar mass (M) of Ba(NO2)2.

To find a molar mass of a compound, break the compound up into component parts so you could see what elements are involved.

If you break Ba(NO2)2 up, you can clearly see that it is composed of Ba, N and O.

You got to find the molar mass of each elements involved. You can identify the molar mass straight away if you look into the periodic table.

Ba = 137.3gmol−1

N = 14.0×2 because there is a number 2 after the closing bracket so 28.0gmol−1

O = There are 2 O atoms inside the bracket and doubled because of the 2 outside the closing bracket, so there are 4 O atoms altogether. 16.0gmol−1×4=64.0gmol−1

So to get the molar mass of Ba(NO2)2, add the molar mass of the elements up. 137.3+28.0+64.0 and that will give you 229.3gmol−1. Therefore the molar mass of Ba(NO2)2 is 229.3gmol−1.

n = 4.50 moles

m = ?

M = 2…
