Moles required = C x V = _______ moles.
RFM of sodium carbonate = _______
mass = moles x RFM. = _______ g.
1
(b) (i) CO32- + 2H+ -> CO2 + H2O
(b) (ii) moles sodium carbonate = C x V = _______
moles HCl = 2 x moles of sodium carbonate = _______
concentration of HCl = moles / volume = _______ mol/dm3

RFM glucose = _______
moles = mass / RFM = _______
moles ethanol = 2 x mol glucose = _______
RFM ethanol = _______
mass of ethanol = moles x RFM = _______ g
Moles carbon dioxide = moles of ethanol = _______
Volume of carbon dioxide = moles x volume (of one mole) = _______ cm3
Volume of carbon dioxide in dm3 - = _______
Calculate the atom economy if ethanol is the only desired product.
Atom economy = mass of desired product / total mass of products x 100 _______ %

Moles Ag = mass / RAM = _______
Moles Cu = Moles Ag / 2 = _______
Mass Cu = Moles Cu x RAM = _______ g
1
Moles of oxygen = mass / RAM = _______
Moles of tin = mass /RAM = _______
Divide both values by the smallest value to get SnO _______
1
Volume in dm3 = volume in cm3 / 1000 = _______
Concentration = mass / volume = _______ g/dm3
Or just use logic if I have a 1/4 of the volume I will have a 1/4 of the mass so the full mass is 4 x mass in 250cm3
