The dilution formula is
mL1 x M1 = mL2 x M2
mL1 x 7.134M = 125 x 1.245
Solve for mL1 = ?
If we want to prepare 125 mL of a 1.245 M aqueous KCl solution from a 7.134 M aqueous KCl solution, how many mL of the 7.134 M solution (rounded with correct number of significant figures) will we need to put in the new solution?
