First determine how many mols you have. The molar mass is about 100 so 340g/100 = 3.40 mols.
Then mols = M x L. You know mols and M, solve for L That wll be
3.40 = 2M x L
M = 3.40/2 - 1.20L or 1200 mL.
Yes, you start by 340 x (1/100) = ? which I've done above.
how much of a .2M solution can you make with 340 g of calcium carbonate ( MW=100.0869)
Do I multiply 340g by 1mole/MW

so how would I find the percentage of that solution
