Question

Calculate the number of C, H, and O atoms in 1.75 g of squaric acid

Answer 1

The formula for squaric acid is C4H2O4. One mole of the acid is 114.06 g. So we have 0.015 mol of squaric acid. That means we have 4(0.015) = 0.06 mol of Carbon and Oxygen, and 0.03 mol of Hydrogen. If you need the exact number of atoms, multiply the moles by Avogadro's number: 6.022 x 10^23
