Question

calculate the number of sulphur amolecules in 32g

Answer 1

32 g → mass. 32 →molar mass of sulfur. Amount (number of moles) → mass/molar mass = 1. Particle (number of atoms X) = amount * avogadro's constant. 1*6.02*10^23 = 6.02*10^23. Oxygen molar mass = (O2) 16 * 2 = 32. Oxygen mass = 32. Repeat steps 3–6.
