P air=29.98 in Hg P H20= 23.060 torr T room= 22.7 C V gas=88.4 mL R=0.08206 L atm/mol K 1. Using the balanced chemical equation write two conversion factors relating mol Mg to mol H2. 2. Covert Vgas, T room, P air, and P H2O into units consistent with the ideal gas law. (1 atm=29.92 in Hg and 1 atm = 760 torr) 3. Calculate the PH2 from the following: P air=P gas= PH2 + PH2O 4. Using these equivalencies...

A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas. The wet gas collected occupies a volume of 283 mL at a pressure of 824 torr and temperature of 28.0°C. The vapor pressure of water at 28.0°C is 0.0372 atm. 1. Calculate the volume (L) that...

A student follows the procedure described in the experiment and collected the following data: 25.5 mL of hydrogen gas collected, barometric pressure of 755 mm Hg, and a temperature of 298 K. Use the ideal gas law (PV=nRT) to answer the questions below. The R value is 0.08206 L atm / Kmol and our data must be in these units. The temperature is given in Kelvin, so no conversion is needed. But the hydrogen gas volume and pressure need conversion...

Need help filling in my data sheet from a lab. My professor said
the pressure was 24.6 inches of Hg and that we needed to convert
that to moles. Im not sure i put that in the correct spot. I
included the lab protocol. Plz plz plz help me fill in the blanks
and let me know if i did something wrong Im very confused haha.
THANKS!!
