Please answer question 31 only!!thanks

In a oxidation reduction titration, during the analysis of an unknown oxalate, how would the calculated percent oxalate of the unknown be affected? 1. The unknown solid sodium oxalate was dissolved in 75 mL of water rather than the 100 mL of water. 2. A few drop of KMnO4 titrant missed the reaction flask containing the unknown sodium oxalate 3. When weighing out the solid unknown sodium oxalate, the actual mass is 0.758 grams. However, the mass is mistakenly recorded in the lab notebook as 0.785 grams.
