Calculate the concentration, in moles per litre, of a solution formed when 13.0 g of calcium hydroxide is dissolved in 5.0 L. Pl
vichka [17]

Answer: The concentration, in moles per litre, of a solution formed when 13.0 g of calcium hydroxide is dissolved in 5.0 L is 0.036 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n}{V_s}

where,

n = moles of solute

V_s = volume of solution in L

moles of Ca(OH)_2 = \frac{\text {given mass}}{\text {Molar mass}}=\frac{13.0g}{74g/mol}=0.18mol

Now put all the given values in the formula of molality, we get

Molarity=\frac{0.18}{5.0L}=0.036M

Therefore, the concentration, in moles per litre, of a solution formed when 13.0 g of calcium hydroxide is dissolved in 5.0 L is 0.036 M
