Enter your answer in the provided box. A gas at 737 mmHg and 37°C occupies a volume of 9.56 L. Calculate its volume at STP. L

Calculate the volume of 85 g of chlorine gas at 73 oC and 1.54 atm.

A gas cylinder that contains argon has an internal volume of 43.8 L. A pressure gauge attached to the cylinder reads 1890 psi (1 atm = 14.7 psi) at 22.3 °C. What mass of argon is contained in the cylinder? mass = g

Three identical balloons (shown below) are filled to the same volume. Temperature and pressure are kept constant (25°C and 101.3 kPa, respectively). Which balloon contains the smallest mass of gas? Explain your reasoning.

0.52 mol of argon gas is admitted to an evacuated 3.00 liter (3.00 × 10-3 m3) container at 20.0°C. What is the pressure of the gas, in atm? 1.00 atm = 1.00×105 Pa. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

STP (standard temperature and pressure) is used as a reference point for the molar volume of an ideal gas. In the USA, most chemists, most general chemistry texts, and OWL use STP=0°C, 1 atm, where the molar volume = volume is 22.7 L/mol. Do not confuse the two. 22.4 L/mol. If the reference pressure is chosen to be 1 bar, the molar A 0.610 mol sample of methane gas occupies a volume of L at STP.

A gas at 721 mmHg and 38°C occupies a volume of 3.94 L. Calculate its volume at STP.

STP (standard temperature and pressure) is used as a reference point for the molar volume of an ideal gas. In the USA, most chemists, most general chemistry texts, and OWL use STP = 0°C, 1 atm, where the molar volume = 22.4 L/mol. If the reference pressure is chosen to be 1 bar, the molar volume is 22.7 L/mol. Do not confuse the two. A 0.580 mol sample of xenon gas occupies a volume of  L at STP.

At STP, 0.332 L of a gas weighs 0.410 g. Calculate the molar mass of the gas. Be sure your answer has the correct number of significant digits. Note: Reference the Fundamental Constants table for additional information. g mol 0 X

The hydrogen gas evolved in a reaction between solid zinc and hydrochloric acid has been collected over water.  The volume of water displaced is equal to 0.587 L.  Given that the gas was collected at a temperature of 30.0°C and the atmospheric pressure was 738 torr, what mass (in mg) of hydrogen gas was collected?  (3 sf) =
