Consider the following set of data where an experiment was done to determine the molarity of a solute. What mass of sample is needed to reduce the %RSD to 0.10% if the sampling constant is 17.3 g? Sample Mass Molarity 1 4.8 0.2561 4.9 0.2432 5.1 0.2522 4 4.8 0.2498 5.0 0.2504 Average 4.92 0.2503 St. Dev 0.130 0.00469 The mass that is required would be x10^ 2. 3.
