**#26.** In honor of the late Alex Trebek, your Chemistry class holds a Jeopardy tournament. The Final Jeopardy statement is "The number of hydrogen atoms in a cup of water." Hint - you might need to use some information from your Quest Packet. A second hint, 1 cup = 236.588 mL and the density of water at room temperature is 1 g = 1 mL.

**#27.** You’re reading the back of your salad dressing bottle just for fun and see that it contains sodium benzoate, which is a preservative. For some nice lunch entertainment, you find the % composition of \( \text{C}_7\text{H}_5\text{NaO}_2 \). What is that answer?

**#28.** Oh no! You and your lab partner forgot to write down the formula of the compound you were analyzing! But as the amazing chemists you are, you use the data from your lab to figure it out. The sample was 4.00 g and contained 1.02 g carbon, 2.72 g of oxygen and the rest was hydrogen. The molar mass of the compound is 141.102 g/mol. Find the empirical and molecular formula for the compound. Format of the molecule is \( \text{C}_x\text{H}_y\text{O}_z \).
