- Use the following balanced chemical equation to answer the below question: 2H&PO4 (aq) +3Mg(OH)2 (aq) 6H2O m + Mg3(PO4)2 (s) The titration of a 14.0 mL sample of H3PO, requires 3.51 mL of 0.400 M Mg(OH)2 to reach the equivalence point. What is the concentration of H3PO,?arrow_forward2. Using the procedure described in this module, a student determined the percent KHP in an impure sample of KHP. A 3.150-g sample of impure KHP required 41.50 mL of 0.1352M NaOH solution for titration. (a) Calculate the number of moles of NaOH required for the titration. (b) Calculate the number of moles of KHP present in the impure sample of KHP. (c) Calculate the number of grams of KHP present in the impure sample. (d) Calculate the percent of KHP in the impure sample, using Equation 8. Equation 8: percent KHP in the impure sample, % = ( mass of KHP in the sample,g/ mass of sample analyzed, g) (100%)arrow_forwardSo I've been trying to figure this one out and I got 0.18, and I just want to check to see if its correct.arrow_forward
