Question

A cubic box has a 0.5 meter side. Find the mass of air in the box in kilograms. (1 Liter of air has a mass of 1.3 g). *

m = 0.1625 kg
m = 162.5 kg
m = 16.25 kg
m = 16 kg

A cubic box has a 0.5 meter side. Find the volume of air in the box in a liter? *

V = 2.5 L
V = 0.125 L
V = 125 L
V = 12.5 L

Answer 1

Answer:
`m=0.1625\ kg,\ ,V=125\ L`

Step-by-step explanation:

Given

The length of the box is
`a=0.5\ m`

1 liter of air has a mass of 1.3 gm

So, the density of air is
`1.3\ g/L`

The volume of the box is

`\Rightarrow a^3=0.5^3\\\Rightarrow 0.125\ m^3\ or\ 125\ L`

Mass of air in the box is

`\Rightarrow m=\rho * V\\\Rightarrow m=1.3* 125\\\Rightarrow m=162.5\ gm\ or\ 0.1625\ kg`
