Name: Total /18 Guacamole Assignment Amadeo Avogadro wants to make guacamole. He needs two avocados per serving of guacamole as well as: 1/2 teaspoon (tsp) of salt; 1.25 cloves of garlic; the juice of one lime; and cilantro to taste. Theoretical: how many avocados does Avogadro need and how many moles of guacamole can he make? Actual: Answer all questions on this sheet and record answers in the table. Include rough work on a separate sheet of paper. Final answers should be rounded to the correct number of significant figures and units should be included. A) Don't get salty [5 marks] 1. What is the chemical formula for table salt? 2. How many moles of salt will you be using in this recipe? 3. How many sodium atoms is that? B) Keep the vampires at bay [8 marks] Garlic's active ingredient is a chemical called alliin (C6H11NO3S). 1. What is the molar mass of alliin? 2. Assume alliin takes up 10.0% (by mass) of the garlic in the recipe. How many moles of alliin are you using? 3. How many atoms of Hydrogen is that?
