The fermentation calculator

A fermentation makes ethanol from sugar, and a still makes a stronger spirit from the broth. You will write the sums and use them for a batch of wine and a batch of spirit.

The idea. From each gram of glucose, at best, $2 \times 46.07 / 180.16$ g of ethanol is made. Ethanol has a density of $0.789$ g per mL.

Your tasks.

1. Finish ethanol_g. It gives the grams of ethanol made in a litre of juice.
2. Finish strength. It gives the strength of the drink in per cent by volume, for a litre.
3. Finish spirit_ml. It gives the millilitres of spirit made from a broth, when a share of the ethanol is collected.
