Moles required = C x V = _______ moles.
RFM of sodium carbonate = _______ 
mass = moles x RFM. = _______ g.

(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

Moles of oxygen = mass / RAM = _______ 
Moles of tin = mass /RAM = _______ 
Divide both values by the smallest value to get SnO _______   

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
