Question

question 5
50.00 ml of a 0.200 m solution of sucrose is diluted to 500.00 ml. what is the molarity of the final solution?
0.0200 m
2.00 m
0.364 m
0.200 m

Explanation:

Step1: Use dilution formula

$M_1V_1 = M_2V_2$

Step2: Substitute values

$M_1 = 0.200\ M$, $V_1=50.00\ mL$, $V_2 = 500.00\ mL$
$0.200\times50.00 = M_2\times500.00$

Step3: Solve for $M_2$

$M_2=\frac{0.200\times50.00}{500.00}$
$M_2 = 0.0200\ M$

Answer:

0.0200 M
