**Question:**How many moles of oxygen atoms are present in 5.148 kg of calcium oxalate?**Answer Choices:**- 6.594 x 10²- 1.608 x 10²- 4.019 x 10¹- 4.019 x 10⁻²- 1.608 x 10⁻⁴**Explanation of Answer Choices:**The image shows a set of multiple-choice answers to a question about calculating the number of moles of oxygen atoms in a given mass of calcium oxalate.- The first option is \(6.594 \times 10^2\)- The second option is \(1.608 \times 10^2\)- The third option is \(4.019 \times 10^1\)- The fourth option (highlighted/selected) is \(4.019 \times 10^{-2}\)- The fifth option is \(1.608 \times 10^{-4}\)This type of question often requires knowledge of molar masses, Avogadro's number, and stoichiometric conversions from mass to moles. It is important to use the molecular formula of calcium oxalate, \( \text{CaC}_2\text{O}_4 \), to determine the number of oxygen atoms per formula unit and to carry out the appropriate calculations based on the given mass. ### Chemistry Question: Mg(OH)₂ Sample Analysis**Question:**A 789.1 ng sample of magnesium hydroxide contains what mass of hydroxide ions?**Answer Choices:**- \( \circ \) \( 5.412 \times 10^{-6} \) g- \( \circ \) \( 4.602 \times 10^{-7} \) g- \( \circ \) \( 3.978 \times 10^{8} \) g- \( \circ \) \( 2.301 \times 10^{-7} \) g- \( \circ \) \( 1.151 \times 10^{11} \) gPlease review the calculations and stoichiometry principles involved in determining the mass of hydroxide ions from a given sample of magnesium hydroxide. Use the molecular weights and Avogadro's number to find the correct answer.

A student performed a similar experiment to the one you performed: They took a crucible and lid, cleaned them, heated them over a flame, and after cooling found their combined mass to be 22.538 g. The student then added a sample of zinc(II) sulfate hydrate (ZnSO4·“n”H2O) to the crucible so the combined mass of the sample, crucible, and lid was 25.896 g. They heated this sample for 10 minutes with the lid ajar, let it cool, and measured the mass of the crucible, sample, and lid to be 25.054 g. a. Based on this experiment, what is the formula for they hydrated zinc(II) sulfate compound? b. The student later looked on the reagent bottle for zinc(II) sulfate hydrate and found the actual formula was ZnSO4·7H2O. If everything had been done correctly, what value should the student have expected for the final mass of their sample, crucible, and lid after heating?
