## How many moles are in sodium sulfate?

Referring to those numbers, the formula Na2SO4 means: two moles sodium (45.98 g), one mole sulfur (32.06 g), and four moles oxygen (64.00 g) combine to form one mole of sodium sulfate (142.04 g).

## 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 grams of sodium sulfate?

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.

## How many ions present in sodium sulphate?

BRIAN M. Sodium Sulfate is an ionic compound formed by two ions, Sodium Na+ and Sulfate SO−24 .

## How do you convert molecular weight to moles?

## How many moles of oxygen are present in 14 grams of Na2SO4?

Question: How many moles of oxygen are present in 14 grams of Na2SO4? 0.099 mol.

## How many grams of sodium sulfate will be formed if you start with 5.00 moles of sodium hydroxide and you have an excess of sulfuric acid?

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.
