There are many solutions. infinite solutions at that. when you solve it it equals itself 2.5w+21= 2.5w+21 so that means all numbers would work as a solution.
Answer:
0.19g/mL
Step-by-step explanation:
The concentration of a solution is how much of a substance in in another substance, usually the amount of solute in a solvent.
The solute is the active ingredient powder. The solvent is the NS solution.
Divide the solute by the solvent.
75g ÷ 400mL
= 75g/400mL Simplify for solute per one unit, 1 mL. Divide top by bottom.
= 0.1875g/mL Round to the nearest hundredth, second decimal place.
≈ 0.19g/mL
Therefore the final concentration is 0.19g/mL.
