molar concentration, solutes, and solvents
Solutions :
Calculate the molar concentration of a solution containing 4.75 of Ca(NO)3 in 0.200 L
Ca(NO)3 = 40.078 + (14.00674 + 15.9994) * 3 = 130.09642
When 130.09642 g of Ca(NO)3 dissolves in 1 liter solvent, solution is 1 M
Therefore, 1 g of Ca(NO)3 dissolve in 1 liter solvent , solution will be 1/130.09642 M
Or, for 4.75 of Ca(NO)3 in 0.200 L, the solution will be 4.5/130.09642 * 0.2
