Question

If 251 mL of 6.0 M H2SO4 is diluted to 500. mL, what is its new molarity?

Answer 1

• 3.0M

Step-by-step explanation:

The dilution formula is:

`M_1* V_1=M_2* V_2`

Where M₁ and M₂ are the molar concentrations and V₁ and V₂ are the volumes of the concentrated and the diluted solutions.

Substitute:

• M₁ = 6.0M

• M₂ = unknown

• V₁ = 251 mL

• V₂ = 500. mL

`6.0M* 251ml=M_2* 500.ml`

Clear M₂ and compute:

`M_2=6.0M* 251ml/500.ml\approx3.0M`
