Question

a compound contains 69.5 percent Oxygen and 30.5% nitrogen and its molecular weight is 92 then formula of compound is​

Answer 1

Answer:

the formula of the compound is N2O4

Explanation:moles of oxygen =69.5/16 = 4.34

                     moles of nitrogen =30.5/14=2.18

ratio of moles of N and O = 2.18:4.34 = 1:2

empirical formula = NO2

n = molecular mass /empirical formula mass

92/46 =2

therefore, 2(NO2)= N2O4
