Question

How many moles of hydrogen are needed to produce 13.78 mol of ethane? 3.445 mol 6.890 mol 27.56 mol 55.12 mol

Answer 1

Given:

• The number of moles of ethane needed to be produced = 13.78
• The molecular formula of ethane is C₂H₆

To find:

The moles of hydrogen gas (H₂) required.

Solution:

• Three moles of hydrogen gas is required to produce one mole of ethane.
• The moles of hydrogen gas required to produce 13.78 moles of ethane = 3*13.78 = 41.34

Answer:

The moles of hydrogen gas (H₂) required = 41.34.
