1
Q
What is concentration?
A
➢The amount of substance dissolved in a certain volume of the solution
2
Q
What is the equation for concentration in g/dm^3?
A
➢ Concentration = amount of solute(g)/volume of solution(dm^3)
3
Q
How much is 1dm^3?
A
➢ 1000cm
4
Q
How can you increase the concentration of an aqueous solution?
A
➢ Adding more solute and dissolving it in the same volume of its solution
➢Evaporating off some of the water from the solution so you have the same mass of solute in a smaller volume
5
