## How many moles of sodium sulfate are there in 10 grams?

Sodium sulfate (Na2SO4 N a 2 S O 4 ) has a molar mass of 142.04g/mol. Therefore, 10g of it represents 10 / 142.04 = 0.07mol.

## How many moles are in 30 grams of sodium sulfate?

30 grams of sodium sulfate divided by its molecular weight – which we found to be 142 – gives us a value of 0.2113 moles.

## How many moles are in 23.5 g of Na2SO4?

1 mole of Na2SO4 contains 7 moles of atoms. Molecular weight of Na2SO4 is (2*23)+(1*32)+(4*16) = 46+32+64 = 142 grams. 142 grams of Na2SO4 contains 7 moles of atoms. So, total number of atoms in 23.5 grams of Na2SO4 is 1.16*6.023*(10^23)=6.99*(10^23) atoms.

## What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

THIS MEANING:  What can you do for severe acne?

## How many grams are in 3 moles of Na2SO4?

No of moles=458/142=3 moles. There are 3 moles in 458 grams of Na2SO4.

## How many moles of sodium are in 2.0 moles of sodium sulfate?

There are 1.20⋅1024 atoms of sodium in 2 moles of sodium.

## How many moles does caoh2 have?

4.5 kg Ca(OH)2 contains 61 moles .

## How many grams of Na2SO4 will be formed if you start with 200 grams of NaOH?

Sodium Sulfate’s Atomic Mass is 142.1 grams/mol. Sodium Hydroxide’s Atomic Mass is 40 grams/mol. The ratio of NaOH to Na2SO4 is 2:1 so we divide the resulting 5 moles of NaOh by 2. 2.5 moles x 142.1 grams/mol (NaSO4)=355.25 or 355.2 grams of Sodium sulfate are produced.
