Question

calculate the mass of mass of oxygen used in the formation of water from 10.2g of Hydrogen. [atomic mass of H=1 and O=16]​

Answer 1

Answer:

80g

Explanation

SINCE WATER IS H2O AND THE RATION OF HYDROGEN AND OXYGEN IS 2:1,

THEREFORE WHEN 10.2g OF HYDROGEN IS BEING USED THEN 10 MOLES OF HYDROGEN TAKE PART IN THE REACTION AND THAT'S WHY FROM THE RATIO WE CAN SAY THAT ONLY 5 MOLES OF OXYGEN TAKES PART,

THEREFORE:-

2*16=80
