50.00 mL of a 0.1001 M solution of HNO3 was prepared by diluting 8.00 mL of a stock solution. Calculate the molarity of the original (stock) HNO3 solution. Write out the problem on paper in order to answer the questions related to the setup and the calculation for this problem. Identify all of the terms in this problem and enter the numerical values (without units) in the appropriate blanks. Enter a question mark for the variable being calculated. Be sure to identify terms for the original solution as M1 and V1, and terms for the final solution as M2 and V2. Do not leave any blank empty. M1 = V1 = M2 = V2 = Rearrange the dilution equation carefully needed to solve for the variable of interest. Identify which terms are in the numerator and which terms are in the denominator after rearranging. Do not leave any blank empty. Use the following abbreviations: original (or stock solution) molarity = M1, volume of original solution = V1, final molarity of new solution = M2, final volume of new solution = V2 Terms in the numerator: , Terms in the denominator: Calculate the result and enter the value in decimal notation (with proper s.f.) in the first blank and the units in the second blank.
