The quantity of alcohol present after a fermentation reaction is called the % alcohol by volume.
This can be calculated from measurements taken using an instrument called a hydrometer. The hydrometer is floated in the liquid sample, before and after fermentation, to measure its specific gravity.
%alcohol by volume = change in specific gravity of liquid x ƒ
Where ƒ is a conversion factor, which varies as shown in the table.

The hydrometer readings are shown below.
Calculate the % alcohol by volume for this sample. (2)

Hydrogels are used in disposable nappies. They are fine powders that can absorb up to 500 times their own weight in water.
A hydrogel is a very long molecule with carboxyl groups at regular intervals along its length. A short section of a hydrogel molecule is shown below.

Hydrogels are extremely good at soaking up water because the water molecules are strongly attached to them.
Using your knowledge of chemistry, comment on how suitable hydrogels would be for absorbing liquids or solutions spilled in a chemistry lab. (3)
