What is the molar mass of C3H8?

a) 44.0 g b) 11.0 g c) 36.0 g d) 6.02 * 1023 g

Answer: (A) 44.0 g/mol

Explanation:

Molar mass of a compound is the sum total of all the individual masses of the constituent elements present in the compound.

Molar mass of C3H8 =

C = 12.0 g/mol

H = 1.00 g/mol

Molar mass of C3H8 = (12*3) + (1*8) = 36 + 8 = 44 g/mol.

Molar mass of C3H8 = 44g/mol

C = 12 g/mol

H = 1 g/mol

C3H8

C: 12 g/mol * 3 = 36 g/mol

H: 1 g/mol * 8 = 8 g/mol

36 + 8 = 44 g/mol

Answer: A) 44.0 g
