18.72 g of a substance 'X' occupies 1.81...

18.72 g of a substance 'X' occupies 1.81 `cm^3`. What will be its density measured in correct significant figures?

A

`10.3g cm^(-3)`

B

`10.34g cm^(-3)`

C

`10.4g cm^(-3)`

D

`10.3425g cm^(-3)`

Text Solution

Verified by Experts

Density `=("mass")/("volume")=(18.72)/(1.81)=10.34 cm^(-1)`
Since volume contains 3 significant figures hence answer will be 10.3 g `cm^(-3)`
