1. What is the % by mass of Mg2+(aq) in the 0.00500 M MgCl2(aq)
solution from Question 1(0.00500 M)? Assume the solution
density is 1.0 g/mL, like water. (3 significant digits, unit
%)
2. Kemmi dilutes the 26 ppm Ag+(aq) solution by twice pipetting 15
mL of solution into a 100 mL volumetric flask. She fills the
remaining volume with water. Use M1V1 = M2V2 with M1 equal to 26
ppm. Solve for the diluted concentration (M2) in units of ppm. (2
significant digits, unit ppm)
(the molarity of the silver cation (Ag+) in the solution = 0.00024
M)
