Question

A compound of molecular mass 78 which have 92.3 % carbon and 7.7 % hydrogen find out molecular and empirical formula of the compound

Answer 1

a compound of molecular mass 78 gm contains 92.3% carbon and 7.7% hydrogen.
so mass of carbon in that compound = 78×92.3/100=72gm. and mass of hydrogen in that compound = 78×7.7/100= 6 gm.
so the molecular formula is C6H6. so it's empirical formula will be CH. hope it helps. plz mark my answer as brainliest.

Answer 2

Answer:

a compound of molecular mass 78 gm contains 92.3% carbon and 7.7% hydrogen.

so mass of carbon in that compound = 78×92.3/100=72gm. and mass of hydrogen in that compound = 78×7.7/100= 6 gm.

so the molecular formula is C6H6. so it's empirical formula will be CH. hope it helps. plz mark my answer as brainliest.
