**Task:**

A 0.296 g sample of carbon dioxide, $\mathrm{CO}_{2}$, has a volume of 525 mL and a pressure of 425 mmHg. What is the temperature, in kelvins and degrees Celsius, of the gas?

**Answer:**

$$pV = \frac{m}{M} RT$$ $$T = \frac{pV}{\frac{m}{M} R}$$ $$M(\mathrm{CO}_{2}) = 44\ \mathrm{g/mol}$$ $$R = 62,364\ \mathrm{mmHg} \cdot \mathrm{l/mol} \cdot \mathrm{K}$$ $$T = \frac{425 \cdot 0.525}{\frac{0.296}{44} \cdot 62,364} = 531\ \mathrm{K}$$ $$\mathrm{^\circ C} = 531 - 273 = 258\ \mathrm{^\circ C}$$
