An industrial chemist synthesised the chemotherapy drug cisplatin from potassium tetrachloroplatinate. Table 1 details the masses involved in a pilot scale-up run of this synthesis.
| Mass in g | |
|---|---|
| Mass of reactant used | 15.00 |
| Actual mass of cisplatin obtained | 8.13 |
| Theoretical maximum mass of cisplatin | 10.84 |
Use the information in Table 1 to calculate the percentage yield of cisplatin in this reaction.
