Calculate the effective molecular weight of air |
|
Answer» Solution :Air is a homogenous MIXTURE. It has 79% NITROGEN and 21% OXYGEN by volume. If we take ONE mole of air, it WOULD contian 0.79 mole of nitrogen and 0.21 mole of oxygen. The weight of one mole of air `=0.79 xx 28+0.21 xx 32` =28.84 Effective molecular weight of air is 28.84 |
