Under conditions of constant temperature and moles of gas, how does the volume of the gas change when the pressure of the gas is decreased by a factor of three? 4. A gas occupies a volume of 2.75 L at 350. mmHg and 200°C. What is the volume of the gas at 550. mmHg...
Part C 1 atm=760 mmHg=101,325 Pa What is the pressure (in atmospheres) of the gas inside the container connected to an open-end, mercury-filled manometer as shown in the picture? (Figure 1 shows 18 cm; cant attach photo) The atmospheric pressure is 0.95 atm. Express your answer numerically in atmospheres.
Given 1 atm = 760 torr = 760 mmHg = 14.7 psi. A balloon sample of helium has a volume of 550 mL at a pressure of 1.0 atm. a. Assuming no change in temperature or amount of helium, what is the new volume in mL if pressure drops to 8.5 psi? b. Assuming no change in temperature or amount of helium, what is the new pressure in mmHg if volume expands to 650 mL?

Predict if the new volume is greater or less than the initial volume, and calculate the...
Part B Review Constants Periodic Table Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average...
