A compound has `40%` of carbon by weight. If molecular weight of the compound is 90, the number of carbon atoms present in 1 molecule of the compound are

A

3

B

2

C

1

D

5

Text Solution

Verified by Experts

The correct Answer is:
A
`{:(ul("Compound"),,ul("Carbon")),("100 gms",-,"40 gms"),("90 gms",-,?):}`
`therefore" wt of carbon = 36 gms per mole"`
`therefore" 3 carbon atoms are present per molecule"`
