Class A balances SR: 6 mg. Min. weighed w/ error of 5% is 120 mg. (Formula: 6mg=0.05X) Percentage of Error (% Error) Maximum potential for error = 5 % % Error equation: SR (SR x 100)/Quantity to be weighed % Error: Actual and Intended Weight ((Actual - Intended)/Intended) x 100 Aliquot Used to measure drug too small to be measured with prescision.
