1.12 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?
Given that the density of methanol is .
So, the number of moles present in the methanol per litre will be or the Molarity of the solution will be :
Now, to make 2.5L of its 0.25M solution:
We will apply the formula:
Hence volume will be required for making 2.5L of methanol 0.25M solution.
