To end up with 100 mL of a 1.0 mg/mL solution of analyte, an analyst should measure _____ of a 15.5 mg/mL analyte solution into a 100-mL volumetric flask and dissolve to the mark.

Answer :

TUTORCONSORTIUM330GO

V₂ = 6.45 mL (volume of analyte)

Calculation

Here we use dilution formula, which is:

C₁V₁ = C₂V₂

where,

C₁ = initial concentration

V₁ = initial volume

C₂ = final concentration

V₂ = final volume

Given data,

C₁ = 1.0 mg/mL

C₂ = 15.5 mg/mL

V₁ = 100 mL

V₂ = ? (to be found)

Putting the values in the formula, we get:

1 × 100 = 15.5 × V₂

V₂ = 100/15.5

V₂ = 6.45 mL

Why would you use a formula for dilution?

A solution is diluted when more solvent is added without increasing solute. The final mixture is thoroughly mixed to make sure that every component is the same.
