Question 1

Yield

Answer 1

Question 2

Percentage yield

Answer 2

(Actual yield / theoretical yield) x100

Question 3

Atom economy

Answer 3

Proportion of atoms in the reactants that are converted into original product

Atom economy = (RFM of desired product / RFM of all products) x100

Question 4

Gas volumes

Answer 4

Volume (dm^3) = moles x 24

Question 5

Concentration

Answer 5

Concentration (mol/dm^3) = moles / volume (dm^3)

Question 6

1dm^3 = ?cm^3

Answer 6

1000cm^3
