30th Jan @ 5:00PM for Grade 1 to 10
Which has more number of atoms, 100 grams of sodium or 100 grams of iron (given atomic mass of Na = 23 u, Fe = 56 u)? Which has more number of atoms, 100 grams of sodium or 100 grams of iron (given atomic mass of Na = 23 u, Fe = 56 u)?
Dear student 23 g of Na = 6.022 × 1023 atoms (1 mole).100 g of Na = ? 100 x 6.022 x 10^23 56 602.2x 10^23 23 = 26.182 ×10^23 = 2.6182×10^24atoms56 g of Fe = 6.022 × 10^23atoms100 g o Fe = ?100 g of Na contain → 2.618 × 10^24atoms100 g of Fe contain → 1.075 × 10^24atoms∴ 100 g of Na contains more atoms.Thanks
