Question

an element has atomic mass 31g/mol , 6.2 gm of this element was found to occupy 1.12 L in gaseous state at STP atomicity of the element is..

Answer 1

Explanation:

Given, 1.12 L≡6.2 g

22.4 L≡

1.12

6.2×22.4

=124 = molar mass

Atomicity=

31

124

=4

(Atomicity is the total number of atoms present in one molecule of an element or a substance. )
