10 Questions
What is the amount of NaOH being added to the solution?
20g
What is the relationship between the mass of solute and the number of moles of solute?
mass of solute (g) / molar mass of solute = number of moles of solute
What is the unit of molarity (M)?
number of moles of solute per liter of solution
Can %w/w of a solution be expressed in molarity?
No
What is the difference between %w/v and molarity?
%w/v expresses solute in grams, while molarity expresses solute in number of moles
What is normality (N) a measure of?
The number of equivalents of solute per liter of solution
What is molality (m)?
The number of moles of solute per kilogram of solvent
How is the molar mass of a solute used in mole calculations?
To convert between mass of solute and number of moles of solute
What is the purpose of using specific gravity or density in solution concentration calculations?
To convert between %w/w and %w/v
Can molarity be calculated from %w/w of a solution?
Only if the specific gravity or density of the solution is known
