Solutions, Concentrations, & Dilution

Question 1

What is a solution

Answer 1

solute + solvent

Question 2

what is a concentration

Answer 2

ratio of the amount of solute to the total quantity of solution

Question 3

what is the difference between a concentrated solution and a diluted solution

Answer 3

concentrated solution: a large amount of dissolved solute in relation to the volume of solution

diluted solution: a small amount of dissolved solute in relation the the volume of solution

Question 4

how do you express concentration

Answer 4

g/L

Question 5

how do we find the concentration

Answer 5

c=m/v

c= concentration
m= mass (solute)
v= volume (solution)

Question 6

what formula do we need to solve dilution problems

Answer 6

c1v1=c2v2

c1=initial concentration
v1=intial volume

c2=final concentration
v2=final volume
