Air has an average molar mass of 29.0 g/mol. The density of air at 0.99atm and 30.0oC is:(Ignore significant figures for this problem.)Select one:a. 29.0 g/Lb. 39.8g/mLc. 1.15g/Ld. 1.37g/mLe. 11.7g/L

Your denist offers homemade "laughing gas" an aneesthesia which is compoased of 2.97g of N2O amd 4.32g of O2 in a 12.5L tank, and is kept at 25.0 degrees C. What is the mole fraction of N2O? Given molar masse: N2O: 44.013g/mol and O2: 31.998g/mol

pressure is constant 4. A sample of the inhalation anesthetic gas Halothane, in a 500-ml cylinder has a pressure of 2.3 atm at 0°C. Wwhat will be the pressure of the gas if its temperature is warmed to 37*C (body temperature)? (Hint: Which law will you apply if the volume is constant?) ype here to search
