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.

Respuesta :

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

Answer:

Number of moles of hydrogen gas produced is 463.

Explanation:

Mass of hydrogen gas measured by chemist = 926 g

Molar mass of hydrogen gas = 2 g/mol

[tex]Moles=\frac{\text{Given mass of compound}}{\text{Molar mass of compound}}[/tex]

Moles of hydrogen gas:

[tex]\frac{926 g}{2 g/mol}=463 mol[/tex]

Number of moles of hydrogen gas produced is 463.
