formulae and amounts of substances

Question 1

gases law equation

Answer 1

pV = nRT

Question 2

yield equation

Answer 2

% yield = (actual yield/theoretical yield) X 100

Question 3

atom economy equation

Answer 3

atom economy = (mass of useful prods/total mass of prods) X 100

Question 4

all mole equations

Answer 4

moles = mass/mr
moles = NO. of particals/avogadros constant
moles = measure/constant
moles = volume of gas (dm3)/24(dm3 mol-1)
moles = conc X volume

Question 5

Avogadro’s law and constant

Answer 5

equal volume of gases at same temp and pressure contains equal number of molecules
6.02 X 10(23)
