part b and c please. how do i solve these
ID-88069042 ± Solution Dilution what is the final volume in mililiters when a 646 L of a 42 0 % (mh) solution is diluted to 21 8 % (mi)? determine the concentration or volume of the initial or dlute solution. s diluted on in other words a dilute solution is "1 of 1 Initial Solution Dilute Solution Part C 4 503 mL NaCI solution is diluted to a volurme of 1.19 L and a concentration of 2.00 M What was the initial concentration? Express your answer with the appropriate units. Hints 0 936 PM 11/2/2017 Type here to searchExplanation / Answer
use this formula...
C1 x V1 = C2 x V2
where C1 and V1 is the concentration and volume of liquid 1 and C2, V2 is concentration and volume of liquid 2.
A) 0.646L = 646 mL
c1v1 = c2c2
42 x 646 = 21.8 x v2
v2 = 1244.6 mL ..... answer
B) c1 x 503ml = 1190 ml x 2M
c1 = 4.73 M
