Please show the calculation (and answer) for the theoretical volume of hydrogen gas produced at STP for trial 1, using the starting mass of magnesium used.
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
Please show the calculation (and answer) for the theoretical volume of hydrogen gas produced at STP for trial 1, using the starting mass of magnesium used.
![Purpose: The purpose of this lab is to determine the percent yield of hydrogen gas produced in the
reaction of magnesium solid with hydrochloric acid under conditions of Standard Temperature and
Pressure (STP).
Directions: Begin by printing out the Generating Hydrogen Lab (pdf file) posted below, and read
the introduction. Please watch the videos posted below, which will show you how the experiment
was done and also explain the calculations needed in this lab exercise. The video explaining the
calculations uses the data given in the lab manual, not the actual data from performing the
experiments. Make sure to use the data given below as your data for trials 1 and 2.
TRIAL 1 (from the 3-part video):
Mass of Mg: 0.083 g
Volume of H2 in cylinder: 73.2 mL
Temperature of H2 gas: 298 K
Barometric Pressure: 761 torr
TRIAL 2:
Mass of Mg: 0.066 g
Volume of H2 in cylinder: 62.0 mL
Temperature of H2 gas: 295 K (note a different temperature here, so there will be a different vapor
pressure of water in trial 2).
Barometric Pressure: 762 torr](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fec1aed6b-83ca-4bd8-a12d-baab2159a4f2%2Fd038ade4-03b7-4f69-b299-dd7a197d8350%2F94rd6ss_processed.png&w=3840&q=75)
