Question

what is the molecular mass of ethane​

Answer 1

Answer:

We also know that 1 mole of C atoms weighs 12.01 g and 1 mol of H atoms weighs 1.0079 g. So, we know the molar mass of ethane also. Or, 30.07 g in 1 mole C2H6. So, we say the molar mass of ethane is 30.07 g/mol (that's grams per mole).
