1.The lab calls for using 10. ml of 50% acetic acid. What is the maximum amount of NaHCO3 that can react with this amount of acid? MWt of NaHCO3=84.0, MWt of acetic acid=60.1 Assume the density of the acetic acid is 1.0 gm/ml

2.The plastic baggies used in the experiment can hold a maximum of 800. ml without leaking. What mass of NaHCO3 will generate this volume of gas
at P=1.00 atm and T=25.0 C? (Assume ideal behavior)

3. If 1.00 ml of CO2 gas leaks out, what mass of CO2 is lost? Use P=1.00 atm, T=25.0 C
MWt of CO2=44.0 (Assume ideal behavior)

4. Why is no buoyancy correction needed for the butane cylinder weighings?

5. Why do gases approach ideal behavior at low pressures and high temperatures?
Explain what is happening at each of these conditions.
