Question

Calculate the molar mass of the following substances.

(a) Ethyne, C2H2​
b) sulphur molecule,s8​

Answer 1

Answer:

(a) Ethyne, C2H2

Molar mass of ethyne

C2H2 = 2 x 12 + 2 x 1

Molar mass of ethyne = 26 g

(b) Sulphur molecule, S8

Molar mass of sulphur molecule,

S8 = 8 x 32 = 256 g

Answer 2

$\red{ 1) \: 26g} \\ \red{2)256g}$
