Calculations ( Lab Data is Linked)
1. Determine the number of moles of hydrogen gas that was produced with the complete reaction of the magnesium metal with excess hydrochloric acid.
2. Using Dalton's Law of Partial Pressure and the vapor pressure of water, determine the partial pressure of dry hydrogen gas.
3. Using the ideal gas law based on the collection of dry hydrogen gas, calculate the value of ideal gas law constant, R.
EXERCISE 1: A quantity of gas occupies a volume of 80 cm3 at a pressure of 750 mm Hg. What volume will it occupy at a pressure of 1.2 atm if the temperature does not change?
EXERCISE 3: A certain amount of gas is at the pressure of 790 mm Hg when the temperature is 25 ° C. Calculate the pressure it will reach if the temperature rises to 200 ° C.

If the partial pressure of oxygen drops below 110 mmHg , passengers become drowsy. If this happens, oxygen masks are released. What is the total cabin pressure at which oxygen masks are dropped? Express answer using two significant figures. So I thought this would be 650 mmHg - 30 mmHg (I got the 30 mmHg from 140 mmHg - 110 mmHg)...but the answer of 620 mmHg was marked incorrect (I also tried 6.2 * 10^2 mmHg, in case it was a significant figure issue, but that didn't work either).
