A student heated different masses of magnesium ribbon in a crucible to react with oxygen from the air to produce magnesium oxide. The results from their investigation are shown in Table 1.
Table 1
| Experiment | Mass of magnesium used / g | Mass of magnesium oxide formed / g | Mass of oxygen reacted / g |
|---|---|---|---|
| 1 | 0.30 | 0.50 | 0.20 |
| 2 | 0.60 | 1.00 | 0.40 |
| 3 | 0.90 | 1.50 | 0.60 |
| 4 | 1.20 | 1.45 | 0.25 |
| 5 | 1.50 | 2.50 | 1.00 |
| 6 | 1.80 | 3.00 | 1.20 |
Draw a graph of the mass of oxygen reacted against the mass of magnesium used.
