# A student heats a sample of pure vanadium metal, \(\text{V}\), in a covered crucible until the metal reacts completely with oxygen to form an oxide. The data from the experiment are shown in the table below.

| Measurement | Mass (\(\text{g}\)) |
| :— | :— |
| Crucible and cover | \(18.20\) |
| Crucible, cover, and \(\text{V}\) | \(20.75\) |
| Crucible, cover, and vanadium oxide | \(22.75\) |

Based on the experimental data, what is the empirical formula of the vanadium oxide product?

A student heats a sample of pure vanadium metal, \(\text{V}\), in a covered crucible until the metal reacts completely with oxygen to form an oxide. The data from the experiment are shown in the table below.

| Measurement | Mass (\(\text{g}\)) |
| :--- | :--- |
| Crucible and cover | \(18.20\) |
| Crucible, cover, and \(\text{V}\) | \(20.75\) |
| Crucible, cover, and vanadium oxide | \(22.75\) |

Based on the experimental data, what is the empirical formula of the vanadium oxide product?

- **A.** \(\text{VO}\)
- **B.** \(\text{VO}_2\)
- **C.** \(\text{V}_2\text{O}_5\)
- **D.** \(\text{VO}_3\)
