Question

what mass of ethane should be taken for same number of h atoms as in 60 grams of methane​

Answer 1

Answer:

Moles of CH4 of 80g = given mass / molar mass = 80/16 = 5

# Molecule of CH4 = 5NA

Atoms of CH4 = 5NA × 4 = 20NA

Given mass / molar mass of C2H6 = given no. / NA

# x / 30 = 20NA / NA

x = 600 g

THEREFORE :

C2H6 = 600g
