Calculate the number of moles for thefollowing:(i) 52 g of He (finding mole frommass)(ii) 12.044 x 10^23 number of He atoms(finding mole from number ofparticles) |
|
Answer» (i). n=m/M =52/4 =13 moles.(ii). 1 mole of He= 6.022 x 10^23 1 atom of He= 1/6.022 x 10^23So, 12.044 x 10^23 atoms of He = 12.044 x 10^23/ 6.022 x 10^23 = 2 moles. |
