One mole of an ideal gas is sealed in a 22.4-l container at a pressure of 1 atm and a temperature of 273 k. the temperature is then increased to 304 k , but the container does not expand. what will the new pressure be?
part a
the most appropriate formula for solving this problem includes only which variables?
enter the required variables, separated by commas (e. g., p, v,t).
q2)a sample of nitrogen gas in a 1.69-l container exerts a pressure of 1.37 atm at 17 ∘c.
-what is the pressure if the volume of the container is maintained constant and the temperature is raised to 327 ∘c?
q3)a gas mixture with a total pressure of 770 mmhgcontains each of the following gases at the indicated partial pressures: 120 mmhg co2, 227mmhg ar, and 190 mmhg o2. the mixture also contains helium gas
-what mass of helium gas is present in a 14.0-l sample of this mixture at 282 k ?
q4)
a
calculate the density of oxygen, o2, under each of the following conditions:
stp
1.00 atm and 35.0 ∘c
express your answers numerically in grams per liter. enter the density at stp first and separate your answers by a comma.
b
to identify a diatomic gas (x2), a researcher carried out the following experiment: she weighed an empty 4.1-l bulb, then filled it with the gas at 2.00 atm and 24.0 ∘c and weighed it again. the difference in mass was 9.5 g . identify the gas.
express your answer as a chemical formula.
