1. The table below lists different types of cleaning agents and chemicals for bar areas and equipment.

In the column Application examples, list 2 applications for use for each product.

In the column Amount of chemical required, calculate the amount of chemical required based on the ratio provided and the quantity of water to be used.

The formula to use is:

Example: ratio 1:50 means 1 part chemical to 50 parts water

To calculate how much chemical is required for 1.000 litres (=1000 millilitres), we divide 1.000 by 50 = 0.020 litres.

Now we know we need 20 ml or 0.020 litres of chemical per litre of water.

If the mixture we require uses 5.000 litres of water then the calculation is: 5.000 (litres of water) divided by 0.050 (Chemical per litre) = 0.100 Litres chemical.

Chemical	Dilution per litre	Water quantity	Amount of chemical required	Application examples
Dishwashing liquid	1:250	50.000 litres
Floor cleaners	1:75	9.000 litres
Bleach	1:50	5 litres
