Question

If 1.3 grams of air has a volume of 1000cm ^3, what is the density of air?

A) 1300g/cm^3
B) 1001.3 g/cm^3
C) 769.23 g/cm^3
D) 0.0013 g/cm^3

Answer 1

D)
Density is equal to mass/volume, so in your case:
density=1.3/1000=0.0013 g/cm^3

Answer 2

Density,
`d=0.0013\ g/cm^3`

Step-by-step explanation:

Given that,

Mass of the air, m = 1.3 grams

Volume of the air,
`V=1000\ cm^3`

The density of the air is given by total mass divided by total volume. Mathematically, it is given by :

`d=(m)/(V)`

`d=(1.3\ g)/(1000\ cm^3)`

`d=0.0013\ g/cm^3`

Hence, this is the required solution.
