Question

Calculate the volume at ntp occupied by 14 gram of nitrogen

Answer 1

28 gram N2 occupies 22.4 lt
so 14 gram of N2 will occupy 11.2 lt

Answer 2

Given wt = 14 g
molecular wt = 28 g/mol 
no of mole = given wt/molecular wt 
= 14/28 = 0.5 

volume = no of mole × 22.4 L 
= 0.5 × 22.4 L 
= 11.2 L
