Question

I have 345 mL of a 1.5 M NaCl solution, if I boil the water until the volume of the solution is 250 mL what will the molarity of the solution be? Round to the nearest whole number

Answer 1

Answer&Explanation:

According to dilution law concentration before dilution is equal to concentration after dilution hence;;

Volume×molarity(before)=volume×molarty(after)

345ml×1.5M=?M×250ml

Cross multiplication

Molarity will be equal to 2.07M
