Question

A compound with a molecular mass of 34g/mol is known to certain 5.88% hydrogen and rest is oxygen. Find the molecular formula of this compound?

Answer 1

Answer:

h2o2

Explanation:

5.88÷1=5.88. and the % of oxygen is 94.12 so 94.12÷16=5.88. now to make it in simple whole no. ratio 5.88 ÷ 5.88 for hydrogen and for oxygen 5.88 ÷ 5.88 this 1 now empirical formul a is HO now molecular formula = molecular mass by empirical formul mass that is 34÷17 =2
