Question 3 (1 point)

What is the mass of four moles of propane gas, C2H6
a)120.32 grams
b)21.80 grams
c)30.08 grams
d)60.16 grams

Answer 1

Option (a) 120.32 grams

Step-by-step 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
