Volume occupied by one molecule of water (density = 1 g `cm^(-3)`)

A

`3.0xx10^(-23) cm^(3)`

B

`5.5xx10^(-23) cm^(3)`

C

`9.0xx10^(-23) cm^(3)`

D

`6.023xx10^(-23)` cm

Text Solution

Verified by Experts

The correct Answer is:
A
`m=Vxxd`
`18=Vxx1 implies V=18 ml`
`6.02xx10^(23)` molecules occupied `=18 cm^(3)`
1 molecule occupied `=18/(6.02xx10^(23))=3xx10^(-23) cm^(3)`
