72.0 ml of a 1.50 M solution is diluted to a volume of 288 mL. A 144 mL portion of that solution is diluted using 185 mL of water. What is the final concentration?

  • Chemistry -

    moles in 72 mL =
    0.072 L x 1.50 M = ?? moles
    M = ??moles/0.288 L = xxM

    moles in 144 mL =
    0.144 x xxM = zz moles
    M = zzmoles/L soln.
