Question

A gas contains 50% Nitrogen,20% Hidrogen and 30% Oxygen in normal conditions.In certain conditions,because of separate action it is obtained water vapor,nitrogen dioxide and amonium.
Find:a) molar mass of the compound before interaction
b) percaentage of components of the initial compound
c) reports in gram and in mole of atoms in each of obtained compounds.

Answer 1

a) Molar mass = 0.5*28 + 0.2*2 + 0.3*32 = 24

b) percentage is given in the task

c) to find grams and mole of reaction products ,the initial weight if gas is needed
