Question

A flask with a volume of 125.0 mL contains air with a density of 1.298 g/L. what is the mass of the air contained in the flask?

Answer 1

A flask with a volume of 125.0 mL contains air with a density of 1.298 g/L. what is the mass of the air contained in the flaskThe given are: 
1.      Mass = ?
2.      Density = 1298 g/L
3.      Volume = 125mL to L
a. 125 ml x 0.001l/1ml = 0.125 L

Formula and derivation: 
1.      density = mass / volume 
2.      mass = density / volume

Solution for the problem: 

1. mass =   1298 g/L / 0.125 L = 10384g
