A student carried out an experiment to determine the enthalpy change of combustion of methanol. The student measured the mass of the spirit burner containing methanol before and after combustion. The recorded mass measurements are shown in Table 1.
Table 1
| Measurement | Mass in g |
|---|---|
| Mass of spirit burner + methanol before combustion | 185.64 |
| Mass of spirit burner + methanol after combustion | 183.87 |
Use the measurements in Table 1 to calculate the mass of methanol, in grams, burned during the experiment.
