a bottle has mass 81.509g when empty. a bottle with pure water has mass 610.5g (density=1.00g/mL). a bottle with isopropanol has mass 498.8g. what is the density of isopropanol?
mass of water = 610.5 g - 81.50 g. Volume of water = mass/density.
mass isopropanol = 498.8 g - 81.50.
density isopropanol = mass/volume = ??
