A chemical measured the amount of barium sulfide produced during an experiment she finds that 823g of barium sulfide is produced calculate the number of moles of barium sulfite produced

4.86moles of barium sulfide are produced

Explanation:

To solve this question we need to convert the mass of barium sulfide (BaS) to moles using the molar mass of BaS:

Molar mass BaS:

1 Ba atom = 137.3g/mol

1 S atom = 32.1g/mol

Molar mass BaS = 137.3 + 32.1 = 169.4g/mol

Moles in 823g of BaS:

823g * (1mol / 169.4g) =

16
