How many molecules are in 25g of na2so4?

The correct answer is: 1,059x10²³ molecules of Na2SO4

Explanation:

Hello! Let's solve this!

The data we have are:

Molar mass Na2SO4 = 142.04 g / mol

Na2SO4 mass = 25 g

Number of moles:

n = 25g / 142.04g / mol = 0.176mol

Each one mole of substance there are 6.02x10²³ molecules

Then we calculate the number of molecules:

molecules = 0.176mol * 6.02x10²³ molecules / mol = 1.059x10²³ molecules of Na2SO4

The correct answer is: 1,059x10²³ molecules of Na2SO4
