# Top response to: how many moles are present in 10g of Na2SO4?

Contents

There are approximately 0.057 moles of Na2SO4 present in 10g.

## Detailed response to the query

According to the question, we are asked to find out the number of moles present in 10g of Na2SO4. The molar mass of Na2SO4 can be calculated by adding the atomic masses of two atoms of sodium, one atom of sulfur, and four atoms of oxygen. It comes out to be approximately 142.04 g/mol. Using this, we can find the number of moles as follows:

Number of moles = Mass of substance / Molar mass of substance

Putting the values of the given data, we get:

Number of moles = 10g / 142.04 g/mol

Number of moles = 0.0704 mol

Therefore, there are approximately 0.0704 moles of Na2SO4 present in 10g.

Sulfates, in general, are important compounds in many applications such as fertilizers, dyes, pigments, and pharmaceuticals. Sodium sulfate (Na2SO4) is used on a large scale in the detergent industry. It is also used in the glass industry as a flux to reduce the melting point of silica and in the textile industry as a levelling agent.

Furthermore, to understand the significance of the mole concept, here is a quote by Richard Feynman:
“Chemistry is the study of the properties of materials and the changes that materials undergo. The most important concept in chemistry is the mole concept because it allows us to connect the properties of materials with the composition of that material.”

| Substance | Molar Mass (g/mol) |
| ——— | —————— |
| Na | 22.99 |
| S | 32.06 |
| O | 15.99 |
| Na2SO4 | 142.04 |

In conclusion, by using the formula of the number of moles, we can easily calculate the number of moles present in a given amount of substance. Na2SO4 is one such important inorganic compound used in various industrial processes. The mole concept forms the basis of stoichiometry, which is widely used for quantitative analysis in chemistry.

10 grams Na2SO4 to mol = 0.0704 mol

Answer:The number of moles in 10 g of sodium sulfate is 0.070 moles.Explanation:We know that the molecular formula of sodium sulfate is $$Na_{2} SO_{4}$$Here the molecule contains 2 atoms of sodium, one atom of sulfur, and four atoms of oxygen.Therefore the molecular mass of sodium sulfate = (2×23)+32+(4×16) = 142 g/mol The given weight of sodium sulfate = 10 gso, the number of moles of sodium sulfate = given mass ÷ molecular mass = $$\frac{10}{142} = 0.070 moles$$

The video “How many moles are in 27.0 g of H2O?” explains how to solve a chemistry problem to determine how many moles are in 27.0 grams of H2O. It emphasizes that the number of moles equals the mass divided by the molar mass of the compound, and to convert grams to moles, the molar mass must be calculated first. The molar mass of H2O is found by adding up the atomic masses of its elements, resulting in a molar mass of 18.015 grams per mole. Dividing 27.0 grams by the molar mass results in 1.50 moles with three significant figures.
