which amongst the following will have more number of atoms1) 6.4g of sulphur2) 9.3g of phosphorus |
|
Answer» 6.4g of sulphur:-Number of mole = weight/ atomic weight = 6.4/32 = 0.2 mole1 mole = 6.023*10^23 atomhence0.2 mole - 0.2*6.023*10^23 atom0.2 mole = 1.2046*10^23 atom 9.3g of phosphorus:-Number of mole = weight/ atomic weight = 9.3/30.9 = 0.3mole1 mole = 6.023*10^23 atomhence0.3 mole =0.3*6.023*10^23 atom0.3mole = 1.806*10^23 atom so, 9.3g of phosphorus has more no. of atoms |
