For ideal gases with each of the following sets of P, V, n, and T, determine the missing number. Note that these different sets of numbers are not related to one another. Pay Du attention to the units. To Ma Part Pressure (P) Volume (V) moles (n) Temperature (Tr a) 3.50 atm 2.20 L 0.29 mol 45.7°C Tas b) 250 kPa 2250 mL 4.08 mol 16.224 c) kPa 0.0420 m 3 5.00 mol 339 K 335.54 1.24 mol 357 K 880 torr 31.37

Consider the apparatus shown below with the valve initially closed. The volume and pressure in each bulb is indicated on the diagram. The temperature remains constant. N2 H2 Valve 3.00 L 6.00 L 1.00 atm 2.00 atm When the valve is opened the two gases mix uniformly. At that point, what is the partial pressure of hydrogen in the apparatus? O 2.00 atm O 1.00 atm O 1.50 atm O 1.33 atm

For many purposes we can treat nitrogen (N₂) as an ideal gas at temperatures above its boiling point of -196. °℃. Suppose the temperature of a sample of nitrogen gas is raised from 27.0 °C to 57.0 °C, and at the same time the pressure is increased by 5.0%. Does the volume of the sample increase, decrease, or stay the same? increase decrease stays the same If you said the volume increases or decreases, calculate the percentage change in % the volume. Round your answer to the nearest percent. x10 X Ś

A sample of gas isolated from unrefined petroleum contains 90.0% CH4, 8.9% C2H6, and 1.1% C3H8 at a total pressure of 307.2 kPa. What is the partial pressure of each component of this gas? (The percentages given indicatethe percent of the total pressure that is due to each component.)
