10 Questions
The total pressure exerted by a gas mixture is equal to the sum of the partial pressures exerted by each component of the mixture.
True
At STP, 1 mole of any gas occupies a volume of 22.4 liters.
True
Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules.
True
The molecular weight of cyclopropane is 42.0 g/mol.
True
According to the Ideal Gas Equation, PV = nRT, where P is pressure, V is volume, n is number of moles, R is the ideal gas constant, and T is temperature in Kelvin.
True
An increase in temperature will lead to an increase in the volume occupied by a gas, assuming other factors remain constant.
True
A decrease in pressure will result in a decrease in the volume occupied by a gas, if all other factors are held constant.
False
The empirical formula of cyclopropane is CH2.
True
The density of NH3 at 100°C and 1.15 atm is 0.638 g/L.
True
In Example 5, the volume occupied by 10.0g of CO2 at 27°C and 2.0 atm is 2.8 liters.
True
Learn about the Ideal Gas Equation and the gas constant, including the relationship between moles of gas, mass of gas, molecular weight, pressure, volume, and temperature. Discover how to calculate the number of moles of a gas in a sample using the Ideal Gas Law.
