like :- particles per mole, coulombs per electron
True because freshwater is regular water
Answer:
15 g of solute (HNO₃) are contained in 100 g of solution
Explanation:
There are many kind of concentrations, Molarity, molality, ppm, percent by volume, percent by mass.
Molarity for example are the moles of solute in 1L of solution.
Molality can be defined as the moles of solute in 1kg of solvent.
ppm are the mg of solute in 1kg of solution.
Percent by volume are the volume of solute (mL) in 100 mL of solution.
In this case, percent by mass is the way to say that x grams of solute are contained in 100 g of solution.
