A carbon compound containing only carbon...

A carbon compound containing only carbon and oxygen has an approximate molecular mass of 290. On analysis. It is found to contain 50% by mass of each element. What is the molecular formula of the compound?

Text Solution

Verified by Experts

The empirical formula `=C_(4)O_(3)`
Empirical formula mass `=(4xx12)+(3xx16)=96`
Molecular mass =290
`n=("Mol.mass")/("Emp.mass")=(290)/(96)=3` approximately
Molecvular formula `=nxx` empirical formula
`=3xxC_(4)O_(3)=C_(12)O_(9)`
