Question

You put 0.025 L of 3.0 M sulfurous acid into a volumetric flask and made a 1.00-L solution. What is the
concentration of the new solution?

Answer 1

Answer:

0.075 M

Explanation:

Step 1: Given data

• Initial concentration of the sulfurous acid solution (C₁): 3.0 M

• Initial volume of the sulfurous acid solution (V₁): 0.025 L

• Final concentration of the sulfurous acid solution (C₂): ?

• Final volume of the sulfurous acid solution (V₂): 1.00 L

Step 2: Calculate the final concentration of the sulfurous acid solution

If we add water to the initial solution, we will get a diluted solution. We can calculate the final concentration using the dilution rule.

C₁ × V₁ = C₂ × V₂

C₂ = C₁ × V₁ / V₂

C₂ = 3.0 M × 0.025 L / 1.00 L

C₂ = 0.075 M
