Answer

Part A

0.098l

Part B

4.902l

In millilitres

98 + 4,902ml

Per litre of finished mixture

19.6ml

How to work it out

  1. 1Parts in total: 1 + 50 = 51
  2. 21 part = 5 l / 51 = 0.098 l
  3. 3A = 1 · 0.098 = 0.098 l · B = 50 · 0.098 = 4.902 l

The formula

a : b → a/(a+b) · mængde

1 : 50 means 1 part of one to 50 parts of the other — 51 parts in total.

C₁ · V₁ = C₂ · V₂

Dilution: the amount of substance is the same before and after — only water is added.

Always follow the manufacturer's instructions. The tool only calculates with the numbers you enter yourself.
