What is the meaning of the term equivalent weight?the weight of the What safety rule do we "bend" in this lab? Are we really breaking that safety rule (hint: is there actual mixing being done?) 3. What would happen if the Mg ribbon were left out and a layer of magnesium oxide formed on it and was not rubbed off with the steel wool? What would happen to your results? Ex-plain. Why is it important that we calculate the volume of "dry" gas? 5. You will measure the change in height of water in your gas buret in mm, but you must con-vert mm of H₂O (this is a measure of pressure) into torr (equivalent to mm Hg). Using the appropriate conversion factors (these can be found in your text book or in a physics text)convert 105.3 mm H₂O to torr. Be sure to show all your work and conversion factors used. 6. In July 2005, Hurricane Dennis hit the Gulf coast of Florida with a central pressure of 949 mbar (= 711.8 torr), what was the pressure in atm? 8. How would your value for equivalence weight be affected if some of the H₂ gas produced during the reaction of Mg(s) and acid escaped from the gas buret?if me! P 9. Given the following experimental values for a gas sample, find the volume of that gas sample under standard temperature and pressure (STP) conditions.

What would be pw in torr if the height of a water column in a gas buret was 26.2 cm?
