To calculate the number of moles in 38.4 grams of ethane (C2H6), we need to use the formula:
moles = mass/molar mass
The molar mass of ethane (C2H6) is:
2(12.01 g/mol) + 6(1.01 g/mol) = 30.07 g/mol
Substituting the values, we get:
moles = 38.4 g/30.07 g/mol
moles = 1.28 mol
Therefore, there are 1.28 moles of ethane (C2H6) in 38.4 grams.
