Question

0.30g of an organic compound containing C,H,O on combustion yeild ed 0.44g CO2 and 0.18g H2O .if 1 mole of compound weight 60g then molecular formula of the compound is
​

Answer 1

Answer:

Explanation:

Moles of C= moles of CO2​=440.44​=0.01 moles

Moles of H=2×moles of H2​O=2×180.18​=0.02 moles

Weight of oxygen = ( 0.30 - weight of carbon and hydrogen ) = (0.3−0.01×12−0.02×1)=0.16 gm

Moles of O=160.16​=0.01 moles

Empirical formula =CH2​O

Empirical formula mass =30 gm

n=3060​=2

Formula=(CH2​O)n​=C2​H4​O2​
