Question

To convert between different solubility units and understand what they mean. The solubility of a solute is the maximum amount that can be dissolved in a given amount of solvent. As the name implies, molar solubility reports the solubility in units of molarity, M. or moles per liter. However, some other common units are grams per liter (g/L) and parts per million (ppm). At 25 degree C .the molar solubility of barium chromate in water is 1.1 times 10-3 M. Calculate the solubility in grams per liter. Express your answer in grams per liter to three significant figures. This part will be visible after you complete previous part(s). This part will be visible after you complete previous part(s).

Explanation / Answer

molar mass of BaCrO4 = 253.4 g/mol solubility = molar mass x molar solubility = 253.4 g/mol x 1.1 x 10^-5 mol/L = 2.79 x 10^-3 g/L
