Forgot How to Do Chemistry
Moles and % composition quiz Version 2 1. Convert 5.3 X 10²³ atoms of CH₄ to moles of CH₄. FORGOT HOW TO DO THIS... 2. What is the percent composition of nitrogen in Ca₃N₂? Ca₃N₂ Ca₃ ↓ N₂ ↓ 3(40.078) + 2(14.0072) = 148.248 MM → 148.248 28.014 / 148.248 = .188 19%
A chemistry quiz worksheet asks students to convert atoms to moles and calculate the percent composition of nitrogen in calcium nitride. A handwritten note says “FORGOT HOW TO DO THIS...” while the second problem shows messy calculations ending in a boxed 19%, humorously capturing panic and uncertainty during a chemistry test.
