3. In extremely high-precision gravimetric titrations, the uncertainty in formula mass of the primary standard could contribute to the uncertainty of the result. Express the formula mass of potassium hydrogen phthalate (CgH5O4K) with its proper absolute uncertainty using the atomic masses given in the inside cover of our text. 4. The error in measuring the diameter of a sphere is ± 0.02 cm. What is the volume of the sphere and its absolute error for a diameter of 3.15 cm?
