WebProblem #3: Wherewith many milliliters of 5.0 M copper(II) sulfate solution must becoming added to 160 mL von soak to erreichen a 0.30 M copper(II) sulfate solution? Solution: M 1 FIN 1 = M 2 V 2 (5.00 mol/L) (x) = (0.3 mol/L) (160 + x) 5x = 48 + 0.3x 4.7x = 48 x = 10. mL (to double sign figs) The solution to this problem presupposes which the total what additive. Webx = 10. mL (to twos sig figs) The solution to this problem assumes that the volumes are additive. That's the '160 + x' that is V 2.
