Molar volume formula

mass→volume

GFM→molar volume

New cards

Molar volume

The volume occupied by one mole of any gas at a certain temperature and pressure. The molar volume is the same for all gases at the same temperature and pressure.

Flow charts analysis

  • Feedstocks (can alternatives be used that are cheaper?)

  • Unreacted reactants (can they be separated and recycled within the flow chart?)

  • By-products (could they be used in a different process or sent to market?)

  • Energy inputs (could they be lowered?)

New cards

% yield

  • Write the balanced equation

  • Identify the reactant that’s in excess and the limiting reactant

  • Calculate the theoretical yield using limiting reactant

  • Calculate the yield (could be masses or moles)

yield= actual yield/theoretical yield*100
