Calculations 3

Question 1

What equation links mass, moles and RFM

Answer 1

Mass = moles (times) RFM

(g) = (mol) times (RFM)

This equation is used to calculate moles in solids

Question 2

What equation links moles, volume, 24dm cubed

Answer 2

Volume = moles (times) 24dm cubed

(dm cubed) = (mol) times (dm cubed)

This is used to calculate gases

Question 3

What equation links moles, concentration and volume

Answer 3

Moles = concentration (times) volume

(Mol) = (mol/dm cubed) times (dm cubed)

This is used to calculate a solution

Question 4

What is 1ml equivalent to

Answer 4

1cm cubed

Question 5

1dm cubed is equivalent to how many cm cubed

Answer 5

1000cm cubed

Question 6

How do you convert between g/dm cubed and mol/ dm cubed

Answer 6

g/dm cubed = Mol/dm cubed (times) RFM

(g/dm cubed) to (mol/dm cubed)

mol/dm cubed = g/dm cubed (divided by) RFM

(mol/dm cubed) to (g/dm cubed)
