Question

if the mass of 10*22molecules of a hydrocarbon is about 1.2 g then the gram molecular mass of hydrocarbon is

Answer 1

Mass of 10²² molecules = 1.2 g

Mass of 6 × 10²³ molecules = 6 × 10²³/10²² × 1.2 g
= 72 g

∴ Gram Molecular mass of given hydrocarbon is 72 g
(2) is the correct option.

Answer 2

Answer:

72 gram

Explanation:

this is the answer for your question and this method and calculation is also correct you can check

but answer written upside my answer calculation is wrong when you will check his calculation then 72 answer will not come
