Calculate final concentration of the solution..?
water is added to 0.150 L of a 6.00 M HCI solution to give a volume of 0.500 L
a 10.0-mL sample of 2.50 M KCI solution is diluted with water to 0.250 L
water is added to 0.250 L of a 12.0 M KBr solution to give a volume of 1.00 L
Answer:
The equation you want to use is this one:
Ci x Vi = Cf x Vf
(initial concentration x initial volume = final concentration x Final volume)
In each of the problems you have been given 3, so just solve for the unknown.
6 M x 0.150 L = Cf x 0.5 L
.9 = Cf x 0.5 L
1.8 M = final concentraion
do the same for the others =)
