A factory produces ammonium nitrate fertiliser. The maximum theoretical mass from one production run is 15.0 tonnes. The factory obtains 12.6 tonnes of ammonium nitrate.
Use the equation:
percentage yield = (mass of product actually made / maximum theoretical mass of product) ×100\times 100×100
Calculate the percentage yield of ammonium nitrate.
