Ideal Gas Law Lab

The Ideal Gas Law Lab taught me that hydrogen is lighter than air, and can be ignited. The materials used for the experiment include 0.05 grams of magnesium, 1M H2SO4, water, a 100mL graduated cylinder, and a beaker. The hydrogen can be ignited with a match. First, the beaker is filled with water. The acid is then added to the graduated cylinder, with about ¾ inch left at the top, which is space for water. Afterward, the magnesium is added to the graduated cylinder, and it is inverted upside down into water. By using a hand to cover the top, it will prevent as much of the liquid spilling as possible. After flipping the graduated cylinder, the acid may have leaked onto the hand, so it must be washed. While pushing the graduated cylinder to the bottom, the magnesium must still be inside of it. The reaction should start at this point, and the graduated cylinder should stay in place throughout the entire reaction. The volume of
The temperature of the water is 293.6 Kelvin. The volume of the gas after the reaction is 57 mL, and the vapor pressure of the water from the graduated cylinder is 2.49 kilopascals.
In comparison, the calculations made were 5.0071 kilopascals of partial pressure of the hydrogen gas. There is 1.578 x 10-3 moles of hydrogen gas collected. Because the equation for the reaction is sulfuric acid plus magnesium metal yields magnesium sulfate and hydrogen gas, the percent yield was 21.1%. A few sources of determinant errors include the measuring of temperature, the amount of acid and water, and the pressures of the room and the water. These errors are reflected when the results show different numbers for every determinant error made.
Overall, the experiment was a success and the hydrogen was successfully confirmed. The theoretical and actual yield are very close, meaning it was an expected result. There were no noticeable errors made in the process of the
