Question

Question 1 (2 points) Suppose a student prepares several different mixtures of solutions of the hypothetical ions \( \mathrm{M}^{\mathrm{n+}} \) and \( \mathrm{XO}_{4}{ }^{\mathrm{y}} \), systematically varying the \( \mathrm{M}^{\mathrm{n+}} \) to \( \mathrm{XO}_{4}{ }^{\mathrm{y}-} \) mole ratio. The absorbances of the resulting solutions are measured and plotted as a function of the mole ratio as shown. What is the \( \mathrm{M}^{\mathrm{n+}} \) to \( \mathrm{XO}_{4}{ }^{\mathrm{y-}} \) mole ratio in the balanced equation? \( 5: 2 \) \( 3: 1 \) \( 2: 1 \) \( 4: 1 \) \( 7: 2 \)
