Answer:
Option (a) 120.32 grams
Explanation:
Data obtained from the question include:
Mole of C2H6 = 4 moles.
The mass of C2H6 can be obtained as follow:
Number of mole of C2H6 = 4 moles
Molar Mass of C2H6 = (12.01x2) + (1.01x6) = 24.02 + 6.06 = 30.08g/mol
Mass of C2H6 =..?
Mass = number of mole x molar mass
Mass of C2H6 = 4 x 30.08
Mass of C2H6 = 120.32g
