Answer #1

Methanol is an organic solvent that is soluble in water. You will know this product because it is the main component of nail polish remover. There are a number of ways of expressing % solution:
When dealing with solutions of liquids in liquids, the v/v system is very convenient: %v/v means volume of solute in 100mL of solution. If you want a 25% v/v solution of methanol in water, you measure out 25mL of methanol and add enough water to give a final volume of 100mL. Is this one of the options you are given.
The expression v/v means volume in volume.

Methanol vapor is burned with excess air in a catalytic combustion chamber. Liquid methanol initially at 25 ◦C is vaporized at 1.1 atm and heated to 100 ◦C; the vapor is mixed with air that has been preheated to 1100 ◦C, and the combined stream is fed to the reactor at 100 ◦C and 1 atm. The reactor effluent emerges at 300 ◦Cand 1atm. Analysis of the product gas yields a dry-basis composition of 4.8% CO2, 14.3% O2, and 80.9%...
