Mole-Mass and Mole-Volume Relationships The Mole-Mass Relationship To convert the mass of a substance to the number of moles of the substance you have to use the molar mass of an element or compound. Mass = # of moles x (mass/1mole) The Mole-Mass Relationship EX: the molar mass of ...
.60 mol SO 2 x 22.4 L SO 2 1 1 mol SO 2 = 13.0 L SO 2 • Find the number of moles in 0.200 L of H 2 gas. 0.200 L H 2 x 1 mole H 2 __ 1 22.4 L H 2 = 8.93 x 10 -3 mol H 2 • Find the number of particles in 3.5 L of chlorine gas (Cl 2 ). 3.5 L ...

The molecules bump into each other and into the container. This causes a build up of pressure. How do you calculate the pressure of a gas? The pressure of a gas can be calculated using the ideal gas law formula. As long as the temperature, volume, and number of moles of the gas are...
Molecules of a gas undergo many collisions with each other and the container walls. True or false: the volume of a gas is independent of the temperature. The relationship between pressure and temperature of a gas, when volume and moles of a gas are...
in which P is pressure in atm (atmospheric units), V is volume in m3(meters cubed), n is the number of moles of the gas, R is the universal gas constant (R = 8.314 J/(mol x K)) and T is temperature of the gas in Kelvin. ...
The volume of a fluid phase can have a sensitive dependence on changes in pressure and temperature. For example,gas formation volume factoris often determined with reasonable accuracy using thereal gasequation of statePV=ZnRTwherenis the number of moles of gas in volumeVatpressurePand temperatureT...
Now, let's look at the ideal gas law, where pressure times volume equalsnnumber of moles multiplied by the universal gas constant (R) times temperature: PV = nRT If we are in a closed system where we aren't losing any gas particles, thennis constant, and R is always constant, so we...
Since the volume of the air decreases, the remaining space in the tank is a vacuum. The problem with this is that a vacuum is a low pressure are so how could the high pressure air and the low pressure vacuum exist next to each other?
The relationship between volume and temperature of a gas, when pressure and moles of a gas are held constant, is: V*T = k. True False The relationship between pressure and temperature of a gas, when volume and moles of a gas are held constant, is: P*...
