a .50 g of NaCl is added to water to create a .50 L solution. what volume of this solution is needed to create a 1.30L solution that is .100M NaCl

  • Chemistry -

    50g of NaCl*(1 mole of NaCl/58.44g of NaCl)=moles of NaCl

    Molarity =moles of NaCl/0.50L


    Once you calculate the molarity using the setup, use M1V1=M2V2 to calculate the volume needed.

    M1=moles of NaCl/0.50L
    V1=?
    M2=0.100M
    V2=1.30L

    Plug in and solve
    V1=(M2/M1)V2
