llowing questions as part of your lab report: 1. A standardized KMNO4 solution can be used to analyse compounds of unknown composition. One such compound is hydrated calcium oxalate, CaC2O4x H2O. The degree of hydration is usually not known and may be determined based on the balanced equation below, by titrating a weighed sample of the hydrated calcium oxalate with KMNO4. 5 H2C2O4(aq) + 2 MnO4 (aq) + 6 H'(aq) 10 CO2(g) + 2 Mn2 (aq) + 8 H2O(1) - If a 0.3215 g sample of CaC204x H2O required 32.28 mL of a 0.02426 M KMNO4 solution, what would be the value of x? (Round your answer to the nearest integer.) Show all your calculations. Write the formula of the hydrate.
