Question

Calculate the number of moles prestin in 0.16 g of ch4

Answer 1

no of moles = weight in gms/molecular mass
molecular mass of CH4 =12+4=16
no of moles = 0.16/16=0.01

Answer 2

Concept

Mole is the amount amount of substance could be a measure of what number elementary entities of a given substance are in an object or sample.

Given

Weight =0.16 g of CH4

Find

The number of moles present in CH4

Explanation

No. of moles = weight in gms/molecular mass

molecular mass of CH4 =12+4=16

Number of moles=0.16/16=0.01 moles
