Question

A chemist wants to make 7,837 mL of a solution with a concentration of 2.45 M.How many liters of a 6.85 M solution should be used to make this solution?

Answer 1

AnswerExplanation:

The liters of a 6.85 M solution that should be used to make the solution can be calculated using the dilution formula.

The formula for calculating dilutions is:

`C_1V_1=C_2V_2`

C₁ = 2.45 M

V₁ = 7837 mL = 7837/1000 = 7.837 L

C₂ = 6.85 M

V₂ = unknown

The unknown volume, V₂ is the required volume needed to make the solution.

Therefore, the V₂ can be calculated using the formula above as follows:
