Mole Calculations

Question 1

Mass vs no. of mol

Answer 1

mass
no. of mol|Ar or Mr

Question 2

Volume vs no. of mol. (GASES only)

Answer 2

volume
no. of mol.|24dm^3

Question 3

Concentration vs no. of mol. (AQUEOUS SOLUTIONS only)

Answer 3

no. of mol
conc (mol/dm^3)|volume (dm^3)

mass in g
conc (g/dm^3)|volume (dm^3)

Question 4

conc. in mol/dm^3

Answer 4

conc (g/dm^3)/Mr

Question 5

approach to mole concept problems

Answer 5

1. Write a BALANCED CHEMICAL EQUATION if it is not given in the question
2. Calculate the NO. OF MOL. (given either mass/volume/concentration)
3. Determine the MOLE RATIO of required product
4. Calculate the REQUIRED VARIABLE (mass/volume/concentration)

Question 6

Answer 6

1000cm^3

Question 7

1kg

Answer 7

1000g
