Calculate the mass, in grams, of copper(II) acetate that must be added to a 300-mL volumetric flask in order to prepare 300 mL of a 0.231 M aqueous solution of the salt. I have a 17.0 % by mass solution of sodium acetate, CH_3COONa (MM = 82.0 g / mo...
The addition of watervapourto a mass of air makes it less dense. Whilst this may appear a bit odd at first this occurs because the molecular mass of water (18) is less than the molecular mass of air (29). The density of humid air can be calculated as the sum of the densities of ...
