A 50 L baby pool has a chlorine concentration of 0.200 M. If 20 L of water evaporated on a hot summer day, 3333 M is the final concentration of the pool.
Molarity is defined as the moles of a solute per litres of a solution.
Molarity is also known as the molar concentration of a solution.
A 50 L baby pool has a chlorine concentration of 0.200 M.
So, the volume of the baby pool is 50L with a concentration of 0.200 M.
[tex]V_1[/tex]=50 L
[tex]M_1[/tex]=0.200 M
If 20 L of water evaporated on a hot summer day, the volume of the baby pool will be 30L and we have to find the concentration of the baby pool after evaporation.
[tex]V_2[/tex]=30 L
[tex]M_2[/tex]=?
Apply the formula,
[tex]M_1V_1[/tex]=[tex]M_2V_2[/tex]
50 L X 0.200 M1 = 30 L X M2
[tex]M_2[/tex] = 0.3333 M
Hence, 0.3333 M is the final concentration of the pool.
