The mass of oxygen gas which occupies 5....

The mass of oxygen gas which occupies 5.6 litres at STP would be

A

The gram atomic mass of oxygen

B

One fourth of the gram atomic mass of oxygen

C

Double the gram atomic mass of oxygen

D

Half of the gram atomic mass of oxygen.

Text Solution

Verified by Experts

The correct Answer is:
D
22.4 L of `O_2` gas at STP has mass = 32 g
5.6 L of `O_2` gas at STP has mass ` = (32 xx 5.6)/(22.4) = 8 g `
8 g of corresponds to half of the atomic mass oxygen .
