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.

Solutions are homogeneous mixtures made up of two non-reacting compounds. The component which is present in large quantity is called as solvent and the component in small quantity is called as solute There are six types of solutions.
1. Gas (solvent) - Gas (solute) Example= Air
2. Liquid (solvent) - Gas (solute) Example= Fizzy Drinks
3. Liquid (solvent) - Liquid (solute) Example= 96% Ethanol in Water
4. Liquid (solvent) - Solid (solute) Example= Sugar in Tea
5. Solid (solvent) - Solid (solute) Example= Brass, 18 caret Gold
6. Solid (solvent) - Gas (solute) Example= Marshmellow
Result:
In equation earth air is solvent (as it is in large quantity) and water vapors (gas) which are in small quantity is solute.
So, it is Gas - Gas Solution.
This is the sample answer:
