- a) moles to grams moles y gm = gram mole (molar mass) by atoms to moles we divide atoms by 6.02x104to converts it into mole, 3 atoms x I mole - = 6.02 1023 atoms I molel .C) mole to atoms mole x 6.02x1013 atoms atoms mole for example a. Imole Iz X 254 gm = 254gm. mole b. 6,02X1024 s-atom a Imol = I moles 6.02x1023 atom C. 2 mole Rb x 6.02x1024 atom = 12.04x10 atom. 23 Imole

2 27 gm Al - So 34 gm Al Inde f 1.26m de F 1 mole Al 34 gmx 1 mole - : 21.26 mole 27 gma 19 gram 19 gm x 1-26mol 23.94 gm Imol
