Question

If the concentrated form of blood expander is 9.0 mol/L and one of your companions, a nurse, tells you that you need to have a final
concentration of 0.145M before you can inject this safely, how much concentrated blood expander do you need to make 2 liters of solution?

Answer 1

Answer:

0.032 L or 32 mL

Explanation:

Use the dilution equation M1V1 = M2V2

M1 = 9.0 M

V1 = This is what we're looking for.

M2 = 0.145 M

V2 = 2 L

Solve for V1 --> V1 = M2V2/M1

V1 = (0.145 M)(2 L) / (9.0 M) = 0.032 L
