Using mass to calculate the volume of a gas You may be asked to calculate the volume of a gas from a given amount stated in grams instead of moles; To answer these type of questions you must first convert grams to moles and then calculate the volume.
Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. Examine kinetic energy and speed histograms for light and heavy particles.

7 Ιουν 2024 · In this lesson we will see and learn how to do the calculations that scientists use to determine the volumes of gases. This is a simplified version of these types of calculations as my students had not yet come across moles or relative formula mass.
Chemists sometimes make comparisons against a standard temperature and pressure (STP) for reporting properties of gases: 273.15 K and 1 atm (101.325 kPa). 1 At STP, one mole of an ideal gas has a volume of about 22.4 L—this is referred to as the standard molar volume (Figure 9.18).
Find the volume the gas will occupy at -39.9 °C if the pressure remains constant. A sample of gas has a volume of 215 cm3 at 23.5 °C and 84.6 kPa. What volume will the gas occupy at STP? At a certain temperature, molecules of methane gas, CH4 have an average velocity of 0.098 m/s.
