Here are a few questions I do not understand:
1. How many moles of ammonia contain 1.51 x 10^24 NH3 molecules?
2. Considering the limiting reactant, how many moles of excess reactant remain after the reaction of 0.600 mol A and 1.400 mol B?
A + 2B --> 3C
3. What volume of carbon monoxide gas at STP reacts to produce 759g of iron?
Fe2O3 + CO --> (1500 degrees C) Fe + CO2
4. The decomposition of 1.500g of potassium chlorate evolved 405mL of oxygen gas. If the calculated volume of oxygen gas is 411mL, what is the percent yield?
5. Considering the limiting reactant, what is the volume of NO gas produced from 40.0L of ammonia gas and 40.0L of oxygen gas? (Assume constant conditions).
Thank you for your help!
