Dilutions Worksheet - Solutions
If 45 mL of water are added to 250 mL of a 0.75 M K2SO4 solution, what will the
molarity of the diluted solution be?
(0.75 M)(250 ml) = M2 (295 mL)
M2 = (0.75 M) (250 mL) = 0.64 M
(295 mL)

Where did the 295ml came from

The amount of material in a particular volume of the solution is measured in molarity that describes as the mole number of solute in 1 liter of solution that is referred to as molarity.

Its original solutions were reduced in volume from 250 mL to 295 mL. You could use the dilution method to calculate the quantity of the solution.

Given:

To find:

Solution:

Using formula:

Apply value into the formula:

Therefore, the final answer is "0.64 mol/L".
