Question

Mass sample 1= .182g 2= .180g Mass of generator and sample before 1=39.593g 2= 39.075g Initial reading of volume of water in co2 1=24.0 ml 2= 26.0 ml Final reading 1=56.5ml 2=41.5ml Volume of co2 collected is ???? Temp of water for both is 21.1C Barometric pressure is 756 Vapor pressure for both is 18.6 Pressure of dry co2 is what? Mass of generator and sample 1=39.563 2=39.005 Mass loss 1=.030 2=.070 Moles of co2 is what??
