Question

Calculate the atomicity of the gas'X',if 1g.of'X' occupies 11,200cc at s.t.p.[at. wt. of 'X'=1]

Answer 1

answer : atomicity = 2

we know, 1 mole of any substance equals 1 gm molecular weight of that substance and it occupies 22.4 litres or 22,400 cc volume at s.t.p

here given, 1gm of the gas 'X' occupies 11,200 cc at s.t.p

it means , 2gm of the gas 'X' occupies 22,400 cc at s.t.p.

hence, from above explanation molecular weight of the gas 'X' = 2 g/mol

and atomic weight of the gas 'X' = 1g/mol

now, atomicity = molecular weight/atomic weight = 2/1 = 2

Answer 2

Answer:

atomicity = 2

Explanation:

hope it helped..arrows are 1 g contains 11200 cc

2 g contains 22400 cc
