Air is approximately 80% nitrogen and 20% oxygen. . The mass of mass of one mole of nitrogen is 28 grams. The mass of one mole of oxygen is 32 grams. To determine the mass of one mole of air, multiply 28 by 0.8, multiply 32 by 0.2, and these two numbers

Mass of one mole air = 28 * 0.8 + 32 * 0.2 = 28.8 grams Mass of one mole of CO2 = 12 + 34 = 44 grams Difference = 44 – 28.8 = 15.2 grams To convert weight in newtons, use the following equation. Weight = kilograms * 9.8 = 0.0152 * 9.8 = 0.14896 N In chemistry, you will learn the one pound is 454 grams. Weight = 15.2 ÷ 454 This is approximately 0.33 lb.
