4. A 200.0mL flask of an unknown gas was placed in a hot water bath. The temperature of the bath was found to be 99°C. The pressure of the flask was 733mmHg. The flask with the unknown gas in it had a mass of 126.593g. The same flask weighed 125.623g when it was empty. Determine the mass of the unknown gas in the flask. Determine the Molar Mass of an unknown gas. Assume that the Ideal Gas Law is obeyed...
A 21.8-L tank of carbon dioxide (CO22) is at a pressure of 9.28 atm and temperature of 19.4∘∘C. (a)Calculate the number of moles of gas in the tank. ______________ mol ( ± 0.02 mol) (b)Obtain the number of grams of carbon dioxide in the tank. Hint: You can obtain the molar mass of CO22 by adding the molar mass of C and twice the molar mass of O. The molar mass of an element is given on the periodic table...
