Answer: 1. 3.23 m
2. 32.4
3. B adding solvent and C removing solute
Explanation:
1. Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent
where,
n = moles of solute
= weight of solvent
Now put all the given values in the formula of molality, we get
2. Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in L
Therefore, the moles of is 32.4
3. Molarity can be decreased by decreasing the moles of solute and by increasing the volume of solution.
Thus adding solvent and removing solute will decrease the molarity.
