0.1535g is the mass of the air contained in the flask.
A substance's density is defined as its mass per unit of volume. Density is most frequently represented by the symbol, however Latin letter D may also be used. Mass divided by volume is the formula for density in mathematics: ρ = M/V. where m is the mass, V is the volume, and ρ is the density.
The given are:
1. Mass = ?
2. Density = 1.228 g/L
3. Volume = 125mL to L
Plugging in the values we get,
ρ = M/V
1.228 = M/ 0.125
M = 0.1535g
Therefore, 0.1535g is the mass of the air contained in the flask.
