Question

A chemist measures the amount of hydrogen gas produced during an experiment. she finds that 926. g of hydrogen gas is produced. calculate the number of moles of hydrogen gas produced.

Answer 1

463 g
1 mole of hydrogen gas has the mass 2 g
926 g/ 2 g = 463 g

Answer 2

Number of moles of hydrogen gas produced is 463.

Step-by-step explanation:

Mass of hydrogen gas measured by chemist = 926 g

Molar mass of hydrogen gas = 2 g/mol

`Moles=\frac{\text{Given mass of compound}}{\text{Molar mass of compound}}`

Moles of hydrogen gas:

`(926 g)/(2 g/mol)=463 mol`

Number of moles of hydrogen gas produced is 463.
