amount of substances

Question 1

concentration

Answer 1

mass (g) / volume (dm3)

Question 2

percentage atom economy

Answer 2

molecular mass of desired product/ sum of molecular of all reactants X 100

Question 3

moles - solution

Answer 3

concentration (moledm-3) X volume (dm3)

cm3 — dm3 (divide by 1000 OR add X10-3
