If 250. mL of nitrogen is collected at 25.0 degrees C and 105 kPa pressure, what will be the volume of the gas at STP?

2. The temperature of CO2 gas at 99.3 mmHg was measured at 455 K. What will be the new temperature if the pressure is adjusted to 202.6 mmHg? Assume constant volume.

If the volume occupied by 0.500 mol of nitrogen gas at 0°C is 11.2 L, then the volume occupied by 2.00 mol of nitrogen gas at the same temperature and pressure will be: A. the data given is not sufficient to determine the volume B. 22.4 L C. 44.
