## 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?

### Solution

25.22mL

Molar mass of methanol (CH_{3}OH) =32 g mol^{–1 }= 0.032 kg mol^{–1}

Molarity of the given solution

Applying M_{2}V_{2}

(Given solution) (solution to be prepared)

= 25.22 mL
