Question

3. If the density of methanol is 0.793 kg it. what is
its volume needed for making 2.5L of its 0.25 M
solution ?​

Answer 1

Explanation:

.25molx32=8gm methanol

=8/.793=10ml methanol

10 ml methanol is required to form 1litre of .25 M soln.

hence to prepare 2.5 litre of .25 M soln of methanol, 10x2.5=25 ml of methanol will be required
