The volume of an empty flask with a one-holed stopper was 285 ml (V1). You heated the flask for 1 minute (T1) and then cooled it in a 22.0°C water reservoir (T2). A volume of 85.0 mL of water was drawn into the flask as the air in the flask cooled (V2 = V1-85.0mL).
a. What was the temperature of the hot air in the flask?
b. What is the value of Charles’ Law constant for the experiment above? k = V1/T1 (that's k = v1 over T1))

1) A weather balloon filled with He gas to a volume of 262 L on a day when the temperature was 18°C. The balloon was only released the next day when the temperature was -10°C. Calculate the new volume of the weather balloon. Assume that the atmospheric pressure remained the same on both days. 2) The volume of an empty flask with a one-holed stopper was 285 ml (V1). You heated the flask for 1 minute (T1) and then cooled...
In Discussion #1, you calculated the volume of gas that your explosive would produce if 1 g of it was used, assuming standard temperature and pressure (STP)and any water produced in the gaseous state. Is this actually accurate, as the gas is usually heated as a result of the explosion, resulting in a much larger volume of gas? But what temperature will the gas reach? Calculate the final volume of the gas produced from 1.00 g of your explosive using...

In a collision of sufficient force, automobile air bags respond
by electrically triggering the explosive decomposition of sodium
azide (NaN3) to its elements. A 43.398 g sample of
sodium azide was decomposed, and the nitrogen gas generated was
collected over water at 22°C. The total pressure was 798.8 mmHg.
How many liters of dry N2 were generated?

i dont understand why the molecular weight i calculated
(42.012 g/mol) for my unknown liquid (acetone) is less than the
actual molecular weight (58.08 g/mol). what errors could i have
made in my lab that would account for the difference.
