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 :

Answer: [tex]m=0.1625\ kg,\ ,V=125\ L[/tex]

Explanation:

Given

The length of the box is [tex]a=0.5\ m[/tex]

1 liter of air has a mass of 1.3 gm

So, the density of air is [tex]1.3\ g/L[/tex]

The volume of the box is

[tex]\Rightarrow a^3=0.5^3\\\Rightarrow 0.125\ m^3\ or\ 125\ L[/tex]

Mass of air in the box is

[tex]\Rightarrow m=\rho \times V\\\Rightarrow m=1.3\times 125\\\Rightarrow m=162.5\ gm\ or\ 0.1625\ kg[/tex]
