Question

To apply the ideal gas law to problems involving temperature, pressure, volume, and moles of a gas.

The four properties of gases (pressure PPP, volume VVV, temperature TTT, and moles of gas nnn) are related by a single expression known as the ideal gas law:

PV=nRTPV=nRT

The variable RRR is known as the universal gas constant and has the value R=0.0821 L⋅atm/(mole⋅K)R=0.0821 L⋅atm/(mole⋅K). The units of RRR dictate the units for all other quantities, so when using this value of RRR, use units of atmospheres for pressure, liters for volume, and kelvins for temperature.

A 16.0 LL gas cylinder is filled with 6.40 molesmoles of gas. The tank is stored at 55 ∘C∘C . What is the pressure in the tank?

Express your answer to three significant figures and include the appropriate units.

A 240. LL kiln is used for vitrifying ceramics. It is currently operating at 1165 ∘C∘C , and the pressure is 1.100 atmatm . How many moles of air molecules are within the confines of the kiln?

Express your answer to three significant figures and include the appropriate units.

A 12.0 LL gas cylinder has been filled with 4.80 molesmoles of gas. You measure the pressure to be 4.40 atmatm . What is the temperature inside the tank?

Express your answer to three significant figures and include the appropriate units.

Definition Definition Law that is the combined form of Boyle's Law, Charles's Law, and Avogadro's Law. This law is obeyed by all ideal gas. Boyle's Law states that pressure is inversely proportional to volume. Charles's Law states that volume is in direct relation to temperature. Avogadro's Law shows that volume is in direct relation to the number of moles in the gas. The mathematical equation for the ideal gas law equation has been formulated by taking all the equations into account: PV=nRT Where P = pressure of the ideal gas V = volume of the ideal gas n = amount of ideal gas measured in moles R = universal gas constant and its value is 8.314 J.K-1mol-1 T = temperature
