A student investigated the energy released when butanol is burned using the apparatus shown below.
The table below shows the results obtained:
| Mass of spirit burner and butanol at start in g | Mass of spirit burner and butanol at end in g |
|---|---|
| 154.68 | 151.48 |
In the student's investigation, the temperature of the 200 cm3 of water increased by 64∘C64^\circ\text{C}64∘C.
Calculate the mass of butanol needed to increase the temperature of the 200 cm3 of water by 1∘C1^\circ\text{C}1∘C.
