Calculate the percent solute of 1.4g of NaCl in 46.6g of saline solution

3.0%

Explanation:

A solution's mass percent concentration, (% m/m), is calculated by observing the mass of solute in grams of obtained in each 100 g of solution. In simple terms, the solution's mass percent concentration is given by the number of parts of solute obtained in every 100 parts of solution, made up of solute and solvent.

Hence the percent m/m concentration of a solution is obtained as;

Mass of solute/ mass of solution × 100/1

From the question, we have,

Mass of solute= 1.4g

Mass of solution= 46.6 g

Therefore, percent m/m concentration of the saline solution=

1.4/46.6 ×100/1 = 3.0%

The percent solute concentration of the solution is 3.0%

water pollution kills aquatic life. aquatic life includes algae and other plant life that use photosynthesis. photosynthesis takes   c02 out of the air.  

c02is a greenhouse gas.
