Question

a marine aquarium is found to contain a salt concentration of 40 ppt. How many grams of salt are in one liter of the solution?

Answer 1

0.04 for the answer to your question

Answer 2

Answer:

There is 40*10⁻¹² g (or 4 * 10⁻¹¹ g) solute in one liter of solution

Explanation:

Concentration measured in very small levels is expressed in terms of ppt i.e. parts per trillion which is the amount (grams) of solute present in a liter (L) volume of solution

$1 ppt = 1*10^{-12} g\ solute/L\ solution$

The concentration of salt in the aquarium is 40 ppt

This implies that there is 40*10⁻¹² g salt in one liter of the solution
