Note that all masses must be measured to the nearest 0.001 g and all volume readings must be to the nearest 0.1 mL. 1) Initial mass of the butane lighter 17.618 g 2) Final mass of the butane lighter 16.972 g 3) Mass of butane collected g 4) Total volume of butane collected mL 5) Volume of butane in liters 21.2L∘C 7) Temperature of water bath in Kelvin K 8) Barometric pressure in inches of Hg 29.20 in. Hg 9) Barometric pressure in mmHg mmHg 10) Vapor pressure of water at temperature from 6. See page 36 in lab manual. 18.880 mmHg 11) Pressure of butane in mmHg mmHg 12) Pressure of butane in atm atm
Calculations. Show all your work with units. 1) Calculate the number of moles of butane collected using PV=nRT. 2) Calculate the experimental molar mass of butane by dividing the mass of butane collected by the number of moles. 3) Calculated the accepted value for the molar mass of butane. 4) Calculate the percent error. 5) Determine the density of butane in g/L.
