Question

The density of oxygen is 2.858 g/L. Volume
occupied by 1 mol of oxygen is
(1) 22,4 L

(2) 11.2 L
(3) 33.6 L
(4) 5.6 L​

Answer 1

Answer:

Density of o

2

=1.429 g/lil

Molar mass = 16×2

=32g/hole

using the formula

Density = mass/volume ⇒ 1.42T=

v

32

volume = 22.39 lit

=22.4 lit

Hence the standard total volume of the

gas o

2

is 22.44 lit
