# A student investigates an unknown volatile liquid by completely vaporizing a sample in a sealed container of fixed volume. The student collects the data shown in the table below.

| Measurement | Value |
| :— | :— |
| Mass of condensed liquid | \(0.460 \text{ g}\) |
| Volume of container | \(246 \text{ mL}\) |
| Temperature of gas | \(300. \text{ K}\) |
| Pressure of gas | \(1.00 \text{ atm}\) |

Based on the data collected, what is the molar mass of the unknown liquid?

A student investigates an unknown volatile liquid by completely vaporizing a sample in a sealed container of fixed volume. The student collects the data shown in the table below.

| Measurement | Value |
| :--- | :--- |
| Mass of condensed liquid | \(0.460 \text{ g}\) |
| Volume of container | \(246 \text{ mL}\) |
| Temperature of gas | \(300. \text{ K}\) |
| Pressure of gas | \(1.00 \text{ atm}\) |

Based on the data collected, what is the molar mass of the unknown liquid?

- **A.** \(46.0 \text{ g/mol}\)
- **B.** \(87.9 \text{ g/mol}\)
- **C.** \(100. \text{ g/mol}\)
- **D.** \(561 \text{ g/mol}\)
