Question

We learned about reaction stoichiometry (how one species relates to another in a balanced chemical equation). We learned how a balanced chemical reaction was like a recipe. The recipe for making liquid nitrogen ice cream is:

3 cups heavy cream + 2 cups milk + ½ cup sugar + 1 tbsp vanilla + N2(l) ice cream for 8 students

If there are 40 students taking this final exam, and assuming all students are eating the ice cream, use the process of dimensional analysis (unit conversion) to calculate how much heavy cream Dr. Lebeau must purchase. Show your work.

Explanation / Answer

how much ehavy cream must we purchase?

3 cups heavy cream + 2 cups milk + ½ cup sugar + 1 tbsp vanilla + N2(l) ice cream for 8 students

factor = 40 students / 8 students = 5x

the reaction must be 5x factored

so

we need

5[3 cups heavy cream + 2 cups milk + ½ cup sugar + 1 tbsp vanilla + N2(l) ice cream for 8 students]

15 cups of heavy cream required
