Amount of Substance - Concentration + Volume Calculations Flashcards
What is concentration?
A measure of the amount of solute dissolved in a given volume of solvent
What is the triangle for solution volume + concentration?
Number of moles of solute (n)
—————————————————————————
Concentration of solution (c) | volume of solution (v)
How do you work out number of moles of solute?
Concentration of solution x volume of solution
How do you work out condensation of solution?
Number of moles of solute / volume of solution
How do you work out volume of solution?
Number of moles of solute / concentration of solution
What is the unit for number of moles of solute?
mol
What is the unit for concentration of solution?
mol dm *-3
What is the unit for volume of solution?
dm *3
How many cm3 is 1 dm3?
1000cm*3
How are concentrated and dilute solutions different?
Concentrated - contains large amount of solute per dm*3 of solvent
Dilute - contains small amount of solute per dm*3 of solvent
