Question

What volume (ml) of a concentrated solution of magnesium chloride (9.00 m) must be diluted to 350.0 ml to make a 2.75 m solution of magnesium chloride?

Answer 1

We can use the formula
c1v1 =c2v2
Where c1 is the concentration and v1 is volume of the concentrated solution
c2 is the concentration and v2 is the volume of the diluted solution to be prepared
9.00 M x V1 = 2.75 M x 350 mL
V1 = 106.9 mL
Volume of 106.9 mL from the concentrated solution should be taken and diluted to 350 mL

Answer 2

The 106.94 ml of 9.0 M concentration magnesium chloride is diluted to 350 ml to make the solution of 2.75 M $\rm MgCl_2$.

For diluting the solution to a specific concentration, following formula is used:

$\rm C_1V_1\;=\;C_2V_2$

C1 and V1 are the concentration and volume of known solution.

C2 and V2 are the concentration and volume of the unknown solution.

From the question,

9 M $\times$ V1 = 2.75 M $\times$ 350 ml

Volume of 9.0 M solution required = 2.75 M $\times$ 350 ml / 9

Volume of 9.0 M solution required = 106.94 ml.

The 106.94 ml of 9.0 M concentration magnesium chloride is diluted to 350 ml to make the solution of 2.75 M $\rm MgCl_2$.
