A sample of drinking water severely contaminated with chloroform , CHCl3 ,is supposed to be carcinogenic in nature . The level of combination was 15 ppm (by mass) .What is the molality of chloroform in the water sample ?
If there is a
You might object to this treatment in that the chloroform solution will have a slightly different density than pure water, but it will have a negligible effect. This is quite probably concentrated enough to taste.
The molality of chloroform is
The formula for molality is
#color(blue)(|bar(ul(color(white)(a/a) "Molality" = "moles of solute"/"kilograms of solute"color(white)(a/a)|)))" "#
Assume that you have 1 L of water. Then the mass of water is 1000 g.
