please help with A and B Calculate the density of oxygen, O_2, under each of the...
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. To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.8-L bulb, then filled it with the gas at 1.40 atm and 30.0 ∘C and weighed it again. The difference in mass was 7.5 g ....
chpt.9 pg 11: Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since density=massvolume The molar mass of a substance, however, is a constant and can be used to identify an unknown gas sample. Molar mass is found by dividing the mass of a sample (in grams) by the number of moles in that sample. The number of moles of gas can be calculated using the ideal...
To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 3.9-L bulb, then filled it with the gas at 1.70 atm and 30.0 ∘C and weighed it again. The difference in mass was 7.5 g . Identify the gas.
To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 2.0-L bulb, then filled it with the gas at 1.00 atm and 28.0 ∘C and weighed it again. The difference in mass was 2.3 g . Identify the gas.
