Question

8. Calculate the molar mass of an alkane with the mole-cular formula C H18.​

Answer 1

Answer: Molar mass = 30 g/ mole CH18

Explanation: The molar mass of CH18 can be calculated by having the sum of the atomic mass of each atom in the compound.

C - 12 (1 ) = 12

H - 1 ( 18 ) = 18

Molar mass = 30 g / mole CH18

Answer 2

Answer:

Molar mass of CH18 =30

Explanation:

CH18

Molar mass of carbon = 12

Molar mass of hydrogen (H) = 1

CH18 = 12 + 1 (18) = 12 +18 = 30
