Question

on. 2. Lake Don Juan in Antarctica is believed to be the saltiest body of water on earth. The lake water is approximately 40% salt. If you collected 125 liters of water from the lake, how many liters of salt would it contain?

Answer 1

Determine the litre of salt in lake water.

`\begin{gathered} (40)/(100)*125=(4)/(10)*125 \\ =(500)/(10) \\ =50 \end{gathered}`

So lake water has 50 litres of salt.
