Amount of Substance - Concentration + Volume Calculations

Question 1

What is concentration?

Answer 1

A measure of the amount of solute dissolved in a given volume of solvent

Question 2

What is the triangle for solution volume + concentration?

Answer 2

Number of moles of solute (n)
—————————————————————————
Concentration of solution (c) | volume of solution (v)

Question 3

How do you work out number of moles of solute?

Answer 3

Concentration of solution x volume of solution

Question 4

How do you work out condensation of solution?

Answer 4

Number of moles of solute / volume of solution

Question 5

How do you work out volume of solution?

Answer 5

Number of moles of solute / concentration of solution

Question 6

What is the unit for number of moles of solute?

Answer 6

mol

Question 7

What is the unit for concentration of solution?

Answer 7

mol dm *-3

Question 8

What is the unit for volume of solution?

Answer 8

dm *3

Question 9

How many cm3 is 1 dm3?

Answer 9

1000cm*3

Question 10

How are concentrated and dilute solutions different?

Answer 10

Concentrated - contains large amount of solute per dm*3 of solvent

Dilute - contains small amount of solute per dm*3 of solvent
