Is 500 ml of a 5m solution is diluted to 1500 ml what will be the molarity of the solution obtained?

If 500 mL of a 5 M solution is diluted to 1500 mL, what will be the molarity of the solution obtained?

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

Answer : B

Solution : Given that, <br> `M_(1)=5M` <br> `V_(1)=500mL` <br> `V_(2)=1500mL` <br> `M_(2) =M` <br> For dilution, a general formula is <br> `M_(1)V_(1)= M_(2)V_(2)` <br> `500xx5M=1500xxM` <br> `M=(5)/(3)=1.66M`
