The answer to “Calculating the Molar Mass of a GasA large evacuated flask initially has a mass of 134.567 g. When the flask is filled with a gas of unknown molar mass to a pressure of 735 torr at 31 °C, its mass is 137.456 g. When the flask is evacuated again and then filled with water at 31 °C, its mass is 1067.9 g. (The density of water at this temperature is 0.997 g/mL.) Assuming the ideal-gas equation applies, calculate the molar mass of the gas.Calculate the average molar mass of dry air if it has a density of 1.17 g/L at 21 °C and 740.0 torr.” is broken down into a number of easy to follow steps, and 105 words.
