Verified answer

Explanation:

To solve this problem, we can use the formula:

M1V1 = M2V2

Where:

M1 = initial concentration

V1 = initial volume

M2 = final concentration

V2 = final volume

Substituting the given values:

M1 = 9.0 M

V1 = 45 mL

M2 = 0.075 M1 = initial volume

M2 = final concentration

V2 = final volume

We know that:

M1 = 9.0 M (because 45 ml of 9.0 M NaCl is the initial solution)

V1 = 45 ml

M2 = 0.075 M (because we want to make a 0.075 M NaCl solution)

V2 = ?

Now, we can solve for V2:

M1V1 = M2V2

9.0 M x 45 ml = 0.075 M x V2

V2 = (9.0 M x 45 ml) / 0.075 M

V2 = 5400 ml or 5.4 L

Therefore, we can make 5.4 L of 0.075 M NaCl solution by diluting 45 ml of 9.0 M NaCl.

Answer:

V2 = ? Therefore, we can make 5.4 L of 0.075 M NaCl solution by diluting 45 ml of 9.0 M NaCl.
