Ok so I have been able to figure out every problem on my study guide except these four. Can anyone help?
1. CO2 diffuses to fill a container in 192 seconds. Another gas diffuses to fill the same container in 300 seconds. What is the molecular weight of the second gas? (The answer is 107.7. I just don't know how to get it)
2. We produce 45 liters of H2O at 280 degrees C and 400 psi. What weight of NH3 did we burn? (answer is 288g)
NH3 + O2 --------- NO2 + H2O
3. We find that we have 3.8g of a vapor in a 350mL flask. If the temperature at which we collected the gas is 100 degrees C and the barometric pressure is 31 inches of Mercury, what is the molecular weight of the gas? (answer is 317)
4. 16L of NH3 will produce ____ liters of H2O in the following...(answer is 24)
NH3 + O2 ---------- NO2 + H2O
