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?

Explanation:

When you form a diluted solution from a mother (concentrated) solution, the moles of solute are determined by the mother solution.

The main equation is:

Then, since the moles of solute is the same for both the mother solution and the diluted solution:

Substitute and solve for the molarity of the diluted solution:

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890
