The number of atoms present in 0.5g atom ofnitrogen is same as the atoms in(1) 12g of C(3) 8g of oxygen(2) 32g of S(4) 24g of Mg |

Answer» The number of atoms in 1 mole of any substance is 6.022× 10^23 atoms . This is according to Avogadro's law and it is referred to as Avogadro's number.Substances with equal moles will have the same the same number of atoms in them. Moles = mass/ molar mass i) Moles of 0.5 g nitrogen: 0.5/14= 0. 0357 moles ii) moles of 12 C molar mass of C = 12= 12/12= 1 mole iii) Moles of 8 g oxygen molar mass of O = 16 8/16 = 0.5 moles iv) Moles of 24 g of Mg Molar mass of Mg = 24 24/24 = 1 mole NB: From the list given there is no element with same number of atoms as 0.5 g of Nitrogen. The question should have read 0.5 MOLES of Nitrogen - then the answer would have been 8g of oxygen 3. 8g of oxygen........ |
