In order to accurately study the effect that changes in pressure, temperature and moles have on volume, chemists will often run their experiments under Standard Temperature and Pressure conditions

Concept #1: Standard Temperature and Pressure

Example #1: A sample of oxygen gas has a measured volume of 325 mL at STP. How many grams are present?

Concept #2: STP and Volume

Example #2: How many moles of chlorine gas occupy a volume of 15.7 L at STP?

Practice: A sample of dichloromethane gas (CH2Cl2) occupies 32.6 L at 310 K and 5.30 atm. Determine its volume at STP?

Practice: Which gas sample has the greatest volume at STP?

Practice: Nitrogen and hydrogen combine to form ammonia via the following reaction:

                      1 N2 (s)  +  3 H2 (g) → 2 NH3 (g)

What mass of nitrogen is required to completely react with 800.0 mL Hat STP?
