Bob wants to make 750 mL of a .250 M sodium carbonate solution. What volume of a 3.50 M stock solution of sodium carbonte should he dilue to 750 mL? How many moles of Na+ are in the 750 mL of diluted solution?
Homework Answers
M1V1 = M2V2
3.5 V1 = 0.25 * 750
V1 = (0.25*750)/3.5 = 53.57 mL
Volume of 3.5 M stock solution of sodium carbonte = 53.57 mL
No fo moles of Na+ in solution = 0.25*0.75 = 0.1875 moles
