Expert Answer:
Mass of 1 mole of phosphorus(P4) = 124g
So 124 g of phosphorus contains 6x1023 molecules
P4 molecule contains 4 atoms
So 124g of phosphorus contains =4x 6 x 1023 atoms
So 12.4g of phosphorus contains = 4 x 6 x 1023 x 12.4 = 2.4x1023 atoms
124
Mass of 1 mole of phosphorus = 124g
So moles in 12.4g phosphorus = 124 = 10 moles
12.4
Mass of 1 mole of phosphorus(P4) = 124g
So 124 g of phosphorus contains 6x1023 molecules
P4 molecule contains 4 atoms
So 124g of phosphorus contains =4x 6 x 1023 atoms
So 12.4g of phosphorus contains = 4 x 6 x 1023 x 12.4 = 2.4x1023 atoms
124
Mass of 1 mole of phosphorus = 124g
So moles in 12.4g phosphorus = 124 = 10 moles
12.4
