Solutions Challenge With Dilutions

***In your answers, include units and proper sig. fig.'s, e.g.,
0.254 M KCl **OR** 17.0 g CaCl2 **OR** 128 mol CuO
Round the molar masses of the elements to the 0.1 place
For example, Hydrogen: 1.0 g/mol; Oxygen 16.0 g/mol

M = mol/L
% = (g solute/g soln) * 100
ppm = (g solute/g soln) * 1,000,000
ppb = (g solute/g soln) * 1,000,000,000
M1*V1=M2*V2

g X <--MM--> mol X <--BCE--> mol Y <--MM--> g Y
