Describe and show your calculations on how you would prepare 1.00L of a 0.50M solution of each of the following
a.) HCl from "concentrated" (12M) reagent.
b.) Sodium Carbonate from the pure solid
c1v1 = c2v2
c = concn
v = volume
Substitute and solve for the one unknown.
You want how many mols? That's mols Na2CO3 = M x L = ?
Then mols = grams/molar mass. You know mols and molar mass; solve for grams Na2CO3.
