Question

The mass of 0.94 mol of H2 is

Answer 1

The mass of 0.94 moles of hydrogen gas (H₂) is 1.88 grams.

Explanation:

To find the mass of a substance given the number of moles, you can use the molar mass. The molar mass is the mass of one mole of a substance and is expressed in grams per mole (g/mol).

For hydrogen gas (H₂), the molar mass is approximately 2 grams/mol.

Given that you have 0.94 moles of H₂, you can use the following formula:

Mass=Number of moles×Molar mass

Substitute the values:

Mass=0.94mol×2g/mol

Mass=1.88g

Finally, The mass of 0.94 mol of H2 is - 1.88 grams.

Answer 2

0.94 mol x 2.02g/mol


Solution: 1.89 g
