A computer model simulates the complete hydrolysis of six identical molecules of an unknown biological molecule, Q.
| Product of complete hydrolysis | Number of molecules produced |
|---|---|
| glucose | 240 |
Explain how the results support the conclusion that Q is a polymer.
Calculate the number of water molecules used to hydrolyse nine molecules of Q completely.
