Question

2- Write the formulae and names of three compounds containing same percentage composition
of C, H and 0
​

Answer 1

Answer:

In C

6

H

12

O

6

we have molecular weight = 180

percentage of carbon =

molecularmass

massofcarbon∗100

percentage of carbon = 40

in CH

3

COOH, molcular mass = 60 and percentage of carbon = 40

in HCOOCH

3

, molecular weight = 60, percentage of carbon= 40

in C

12

In H

22

O

11

, molecular weight = 342, percentage of carbon = 42.15
