Question
If 500 mL of a 5 M solution is diluted to 1500 mL, what will be the molarity of the solution obtained?
Options
1.5 M
1.66 M
0.017 M
1.59 M
Solution
1.66 M
Explanation:
The relation between molarity and volume is given as,
M1V1 = M2V2
On substituting the value in the above equation, the pol can be calculated as
5 × 500 mL = M2 × 1500 mL
M2 = `(5 xx 500)/1500` = 1.66 M
