The structure of isobutyl group in an organic compound is

A

`((1.2)/(35))N_(A)`

B

`(1)/(1.2)((1)/(35))^(2)N_(A)`

C

`(1.2)/((35)^(2))N_(A)`

D

`1.2N_(A)`

Text Solution

Verified by Experts

The correct Answer is:
3
Mass of one drop `=(2)/(35)xx1.2=(2.4)/(35)g`
Moles of liquid in one drop `=(2.4)/(35xx70)=(1.2)/(35^(2))`
`:. ` Molecules `=(1.2)/(35^(2))xxN_(A)`
