Question

Calculate number of molecules

present in 6.2 g of phosphorous.​

Answer 1

Explanation:

Atomic mass of phosphorus is 31 u

Molecular mass of P4 = 31 X 4 = 124 u

Molar mass of P4 = 124 g

1 mole P4 molecule is =124g

124g of P4 contains 6.023 X 1023 molecules of P4

62 g of P4 contains -62 X 6.023 X 1023 /124 = 3.0115 X 6.023 X 1023
