1)At 25.0∘C, the molar solubility of silver chromate in water is 1.10×10−12M . Calculate the solubility in grams per liter.
given
molar solubility of silver chromate = 1.1 x 10-12 M
the units of molar sulibility is M = mol / L
so
molar solubility of silver chromate = 1.1 x 10-12 mol/L
we know that
mass in grams = moles x molar mass
so
to get the solubility in grams
the formula is
solubility in grams = molar solubility x molar
mass
we know that
molar mass silver chromate = 331.73 g/mol
so
solubility in grams = 1.1 x 10-12 x 331.73
solubility in grams = 3.65 x 10-10 g/L
so
the solubility in grams per liter of silver chromate is 3.65 x 10-10
