A student measured the mass of an empty micropicnometer to be 2.000g. A student places 0.500mL of citric acid solution into a micropicnometer. The student reweighed the micropicnometer and found the mass of the citric acid solution and micropicnometer to be 2.525g.  Calculate the density of the citric acid solution in g/ml. part b) A student measured the mass of an empty micropicnometer to be 2.000g. A student places 0.500mL of citric acid solution into a micropicnometer. The student reweighed the micropicnometer and found the mass of the citric acid solution and micropicnometer to be 2.525g.    A student titrates 0.101mL of citric acid solution using the standardized 0.1M solution (use the exact concentration calculated from the previous titration problem). The sample required 0.819mL of NaOH solution to reach the end point.   Given the following chemical equation.   NaOH   +  H3C6H5O7 →  Na+ +   H2O  +   C6H5O73-   Given the above information. Calculate the mass of citric acid in the 0.101mL citric acid solution.
