At a certain temperature and pressure, a 1.00 mol sample of argon gas is pumped into a 22.4 L rigid box that already contains 1.00 mol of nitrogen gas.  We would expect the argon gas to: Group of answer choices decrease the total gas pressure in the box by a factor of 2 occupy the entire 22.4 L volume of the box. increase the total gas pressure in the box by a factor of less than 2. spread out into the box, but the actual volume occupied but he gas cannot be known without pressure information. occupy only 11.2 L of the box.

What pressure is exerted on the bottom of a 0.5m wide by 0.9 m long gas tank that can hold 50kg of gasoline by the weight of the gasoline in it when it is full?
