Rock Ethan Galloghy University Science Books presented by Sapling Learning How many milliters of 10.5 M HCl(aq) are needed to prepare 260.0 mL of 1.00 M HCl(aq)? Number m L What is the concentration of a solution made by diluting 25 mL of 6.0 M HCI to a final volume of 750 mL? Number Previous Give Up & View Solution O Check Answer 0 Next Exit Hint

Explanation / Answer

M1V1 = M2V2
M1 = 10.5M
v1 = ?
M2 = 1.00M
V2 = 260 ml

10.5*V1 = 1*260
V1 = 24.8 ml
24.8 ml of 10.5 M HCl required
..............................................

M1V1 = M2V2
M1 = 6 M
v1 = 25 ml
M2 = ?
V2 = 750 ml

6*25 = M2 *750
M2 = 0.2 M
the concentration of diluted solution is 0.2M
