Answer 1

Standard molar volume In any gas is

= volume occupied by 1 mole that is 32g of the O2 gas at NTP/STP

= Mass/density

▶density = mass/volume ➡volume = mass/density

= 32/1.429

= 22.39 L

Answer 2

hi

here is your answer

Given,density = 1.429g/L

Molar mass of O2 is 16×2= 32g/mole

So volume = Mass / density

= 32/1.429

=22.39

=22.4 litre
