Explanation:

<em>How many grams of hydrogen are in 10.45 moles of C₃H₈?</em>

Step 1: Calculate the moles of atoms of hydrogen

The molar ratio of C₃H₈ to H is 1:8.

10.45 mol C₃H₈ × 8 mol H/ 1mol C₃H₈ = 83.60 mol H

Step 2: Calculate the mass corresponding to 83.60 moles of hydrogen

The molar mass of hydrogen is 1.008 g/mol.

83.60 mol × 1.008 g/mol = 84.27 g
