Answer :
The receipe that should be used in a commercial saline solution is Option a; 0.9 g of salt and 100 g water.
Recipe used in a commercial saline solution:
Since 0.9% by mass represents a sort of concentration.
A percent by mass represents, the grams of solute that are consist in 100 g of solution, so:
Now
Mass of solute = 0.9 g
So,
Mass of solvent = Mass of solution - mass of solute
100 g - 0.9g = 99.1 g of water
Mass of solution = 100 g
Therefore, the option b is correct.

Answer:
Option a; 0.9 g of salt and 100 g water
Explanation:
0.9% by mass indicates a sort of concentration.
A percent by mass shows, the grams of solute which are contained in 100 g of solution, so:
Mass of solute = 0.9 g
Mass of solvent = Mass of solution - mass of solute
100 g - 0.9g = 99.1 g of water
Mass of solution = 100 g the best option that matches this, is B.
There are other types of concentration in addition to the percentage by mass
% by volume → mL of solute in 100 mL of solution
% by mass/volume → grams of solute in 100 mL of solution
