Calculate (1) the number of moles and (2) the volume at STP of 0.52g of acetylene.

Text Solution

Verified by Experts

(1) Gram-molecular mass of acetylene is 26g.
`therefore`Number of gram-mole present in 0.52 g of acetylene
=0.52/26=0.02
(2) At STP, 26g of acetylene occupies a volume of 22.4 L.
`therefore`At STP, 0.52g of acetylene occupies a volume of
`=(22.4xx0.52)/(26)L=0.448L`.
