A tank of nitrous oxide (N2O) used as an anesthetic has a pressure of 48 psi. What is the pressure in torr?

What is the new volume (in L) of an 34.7 L sample of carbon monoxide, CO, if the pressure changed from 744 mm Hg to 860 mm Hg at constant temperature?

For the reaction H2(g) + Br2(g) =2 HBr(g), Kc = 81.4 at 385°C. If [H2] = [Br2] = [HBr] = 2.4 x 10-4 M at 385°C, which one of the following is correct? %3D [HBr] increases as the system approaches equilibrium. [H2] and [HBr] decreases as the system moves toward equilibrium. [H2] and [Br2] increases as the system approaches equilibrium. There is not enough information given to make a determination. [HBr] and [Br2] increases as the system approaches equilibrium. The system is at equilibrium.

A sample of ammonia (NH3), a colorless gas with a pungent odor, occupies a volume of 8.00 L at a pressure of 655 mm Hg and a temperature of 25°C. What volume, in liters, will this NH3 sample occupy at the same temperature if the pressure is increased to 725 mm Hg? Volume
