An element has atomic mass `31`. Mass of `1.12 "litre"` at `STP` of vapours of this element weighs `6.2 g`. Find the atomicity of this element.

Text Solution

Verified by Experts

The correct Answer is:
4

`:' 1.12` litre `-= 6.2g`
`:. 22.4` litre `-= (6.2 xx 22.4)/(1.12) = 124`
`:.` Atomicity `= (124)/(31) =4`
