Question

a flask with a volume of 125 mL contains air with a density of 1.197 g/L. what is the mass of the air contained in the flask?

Answer 1

Density can be defined as the mass of a sample present per unit volume.

`Density = (Mass)/(Volume)`

Given the volume of air = 125 mL

Converting air from mL to L,

`125 mL * (1 L)/(1000 mL) = 0.125 L`

Density of air = 1.197 g/L

Calculating the mass of air from density and volume:

Mass of air =
`0.125 L * (1.197g)/(L) =0.150 g`

Therefore, the mass of 125 mL of air with a density of 1.197 g/L is 0.150 g
