Concentration of solutions Flashcards
1
Q
What is the concentration of solutions measured in
A
Grams per decimetre cubed (g/dm^3)
or
Moles per decimetre cubed (mol/dm^3)
2
Q
How do you calculate a solute’s mass in a certain volume of a solution when you know the concentration
A
Mass of solute = volume of solution x concentration
3
Q
Give 2 ways to increase the concentration of an aqueous solution
A
1) add more solute + dissolve it in same volume of the solution
2) evaporate more water from solution: same volume of solute in less volume of water
