1. A student performs the experiment according to the instructions in this experiment. (SHOW WORK in spaces provided)

a. The weight of magnesium ribbon used is 0.0328 grams. How many moles of hydrogen could be collected if all the magnesium reacts with the HCl?

b. The thermometer reads 25.0°C. What is the temperature on the Kelvin scale?

c. What is the vapor pressure of water at 25.0°C?(use a textbook: express answer in torr)

d. The barometer reads 760. torr. What is the pressure, in atmospheres, of dry hydrogen at 25°C ?

e. It takes 33.1 milliliters of water to fill the buret to the mark where the water level was equal inside and outside the buret. What is the volume of hydrogen in liters?

f. Calculate the value for the gas constart, R in units of L.atm/K/mol

#### Solution Summary

This solution outlines all of the necessary calculations for a typical "Calculation of a Gas Constant" lab report. The gas constant is calculated given a mass of Mg and the volume of hydrogen gas evolved from reaction of Mg with HCl.
