Forgot How to Do Chemistry

Moles and % composition quiz Version 2 1. Convert 5.3 X 10²³ atoms of CH₄ to moles of CH₄. I FORGOT HOW TO DO THIS... 2. What is the percent composition of nitrogen in Ca₃N₂? Ca₃N₂ Ca₃ 40.078 N₂ 2(14.007) MM 148.248 28.014 / 148.248 = .188 19%

A chemistry quiz asks the student to convert atoms to moles and calculate the percent composition of nitrogen in calcium nitride. The handwritten note says “I FORGOT HOW TO DO THIS...” while the attempted calculations end with a boxed 19%, making the joke about being overwhelmed and unsure during a test.
