The molarity of the solution is 0.1625M.
<h3>What do you meant by Molarity</h3>
Molarity is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of solute per litres of a solution .
Molarity → no of moles / Volume (L)
SI unit of Molarity is M or mol/ L
We have given here the mass of solution is 3.10×10²g .
molality of the solution is 0.125m
Molality → no of moles / mass in kg
→ 0.125×3.10×10²/ 1000
→ no.of moles = 0.0162
For molarity we can assume volume as 1000 ml .
Molarity = 0.0162×1000/ 100
Molarity →0.162 M.
So, the molarity of solution will be 0.162M.

Answer: The results agree with the law of conservation of mass
Explanation:
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. On the reactant side, the total mass of reactants is 14.3g and the total product masses is also 14.3g. That implies that no mass was !most in the reaction. The sum of masses on the left hand side corresponds with sum of masses on the right hand side of the reaction equation.
The density of He is 1.79 x 10⁻⁴ g/mL
In other words in 1 mL there's 1.79 x 10⁻⁴ g of He.
To fill a volume of 6.3 L the mass of He required
= 1.79 x 10⁻⁴ g/mL * 6300 mL
= 11 277 * 10⁻⁴ g
Therefore mass of He required = 1.1277 g of He
