Question 3
A sample of gas occupies 10.0 liters at 240 o C under a pressure of 80.0 kPa. At
what temperature will the gas occupy 20.0 L if the pressure is increased to 107kPa? (Write your answer in scientific notation using the "^"symbol i.e. 2.54 X 10^4. Make sure to round correctly)
Temp in K =
Temp in o
C =

Question 4
How many moles of hydrogen are present in a 5.00L container at a pressure of 0.526 atm at 26.0 °C

Question 6

200.1
40.7
314

Question 2
Fluorescent light bulbs contain a mixture of mercury vapor and a noble gas such as argon. How many moles of argon are in a 121 mL bulb with a pressure of argon gas of 325 Pa at 40 o C?
Please answer using the correct unit after your numerical result

Question 7
A. What minimum volume in liters of oxygen gas at STP must be added to
completely react 1.90 X 10⁶ L of CH2CH2 gas at STP? Your answer should be in
scientific notation. CH2CH2 (g) + O2 (g) ---> C2H4O(g)
_____________ L of O2
B. What is the mass in kilograms of C2H4O that would be produced if all of
the CH2CH2 gas reacted completely? Your answer should be in standard notation NOT scientific notation.
_____________ Kg of C2H4O

Question 5
Sulfur is used in the production of vulcanized rubber, detergents, dyes,
pharmaceuticals, insecticides and many other substances. The final (unbalanced)
reaction step in the Claus method for making sulfur is:
SO2(g)+H2S(g) --> S (s) + H2O (I)
a.What minimum volume of sulfur dioxide at STP would be necessary to produce 82.5 kg of sulfur? Indicate your answer using scientific notation (i.e. 2.53 X 10⁸)
__________ L of SO2
b. What maximum mass of sulfur in kilograms could be produced by the reaction of 1.3 X 10⁴ m³ of SO2 (g) with 2.5 X 10⁴ m³ of H2S (g), both at STP?
Indicate your answer using scientific notation (i.e. 2.53 X 10⁸)
__________ kg of S
