The concentrationof the alkane C20H42 (FM= 282.55) in a particular sample in rain water is 0.2ppb. Assume that the density of the rain water is close to 1.00 g/ml and find the molar concentration of C20H42.
A sparingly soluble salt gets precipitated only when the product of concentration of its ions in the solution (Qsp) becomes greater than its solubility product. If the solubility of BaSO4 in water is 8 × 10-4 mol dm-3, calculate its solubility in ..
