Question

a compound contains carbon and oxygen in the mass ratio 3 ratio 1 find the molecular formula of the compound​

Answer 1

Answer:

Atomic no. of carbon is 6

and atomic no. of oxygen is 8

therefore according to their mass ratio

3:1there is no compound of carbon and oxygen in the ratio 3:1

but instead there is carbon and hydrogen in the ratio 3:1 the compound is CH₄

C=12 , H= 1×4 so the ratio is 12:4 = 3:

follow me please

Answer 2

Answer:

atomic no. of carbon is 6

and atomic no. of oxygen is 8

therefore according to their mass ratio

3:1

then 3×6/1×1 = 18÷1 = 18 amu

therefore
