Dilutions Practice

If I have 340 mL of a 0.5 M NaBr solution, what will the concentration be if I add 560 mL more water to it? (total final volume 340 mL + 560 mL)​ 2 decimal places (a)   M

If I dilute 250 mL of 0.10 M lithium acetate solution to a volume of 750 mL, what will the concentration of this solution be?​ (3 decimal places) (a)   M

If I leave 750 mL of 0.50 M sodium chloride solution uncovered on a windowsill and 150 mL of the solvent evaporates, what will the new concentration of the sodium chloride solution be? (750mL - 150 mL = V₂) 3 decimal places​ (a)   M

If you dilute 175 mL of a 1.6 M solution of LiCl to 1.0 L, determine the new concentration of the solution. 2 decimal places​ (a)   M
