Question

by a single expression known as the ideal gas law: PV = nRT The variable R is known as the universal gas constant and has the value R = 0.0821 L · atm/(mole · K). The units of R dictate the units for all other quantities, so when using this value of R, use units of atmospheres for pressure, liters for volume, and kelvins for temperature. Part A A balloon is floating around outside your window. The temperature outside is -15 °C , and the air pressure is 0.800 atm . Your neighbor, who released the balloon, tells you that he filled it with 4.60 moles of gas. What is the volume of gas inside this balloon? Part B A 16.0 L gas cylinder is filled with 10.0 moles of gas. The tank is stored at 9 °C . What is the pressure in the tank? Express the pressure numerically in atmospheres. Part C A 300 L kiln is used for vitrifying ceramics. It is currently operating at 1405 °C , and the pressure is 0.9750 atm . How many moles of air molecules are within the confines of the kiln? Express your answer numerically in moles. Part D A 20.0 L gas cylinder has been filled with 4.40 moles of gas. You measure the pressure to be 4.90 atm . What is the temperature inside the tank?

PV = nRT
The variable R is known as the universal gas constant and has the value
R = 0.0821 L · atm/(mole · K). The units of
R dictate the units for all other quantities, so when
using this value of R, use units of atmospheres for
pressure, liters for volume, and kelvins for
temperature.
Part A
A balloon is floating around outside your window. The temperature outside is -15 °C , and the air pressure is 0.800 atm .
Your neighbor, who released the balloon, tells you that he filled it with 4.60 moles of gas. What is the volume of gas inside
this balloon?
Part B
A 16.0 L gas cylinder is filled with 10.0 moles of gas. The tank is stored at 9 °C . What is the pressure in the tank?
Express the pressure numerically in atmospheres.
Part C
A 300 L kiln is used for vitrifying ceramics. It is currently operating at 1405 °C , and the pressure is 0.9750 atm . How
many moles of air molecules are within the confines of the kiln?
Express your answer numerically in moles.
Part D
A 20.0 L gas cylinder has been filled with 4.40 moles of gas. You measure the pressure to be 4.90 atm . What is the
temperature inside the tank?
