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
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
Plug in and solve
