Calculate the number of atom in each of the following a. 52 moles of He. b. 52g of He c. 0.1 mole of H2SO4 |
|
Answer» a) 1 mole of He has 6.023 X 10^23 atoms. 52 MOLES of He has 52 x 6.023 x 10^23 = 313.196 x 10^23 atoms. b) 52 g of HE1 mole of He has 4 g. 4 g = 6.023 x 10^2352 g = 52 x 6.023 x 10^23 / 4 = 78.299 x 10^23 atoms..C) 0.1 mole of H2SO4 = 1 mole of H2SO4 contains 6.023 x 10^230.1 mole of H2SO4 contains 6.023 x 0.1 x 10^23 = 0.6023 x 10^23 |
