Question

If the density of methanol is 0.793 kg L^–1, what is its volume needed for making 2.5 L of its 0.25 M solution?

easy

Solution

Correct option is

25.22mL

Molar mass of methanol (CH₃OH) =32 g mol^–1= 0.032 kg mol^–1

Molarity of the given solution

Applying M₂V₂

(Given solution) (solution to be prepared)

= 25.22 mL
