Question

Calculate the molar concentration of a potassium sulfate, K₂SO₄, solution made up as indicated below. Round the answer to the correct number of significant figures. Calculate the absolute uncertainty in the molar concentration using the absolute uncertainties for each quantity. Does the calculated absolute uncertainty support the number of significant figures you rounded to? Why or why not.

Mass = 0.0731 g (+/- 0.5 mg)

Volume = 500.00 mL (+/- 0.20 mL)

Molar mass + 174.259 g/mol (+/- 0.005 g/mol)
