Question

9.3 gram of AlPO4 calculate the number of each particle ​

Answer 1

Moles of AlPO4=9.3/122

so moles of Al = 1 X 0.07 = 0.07

no. of atoms of Al = 0.07 x NA = 4.214 X 10 ^22

moles of P = 1 X 0.07 = 0.07

no. of atoms of P = 0.07 x NA = 4.214 X 10 ^22

moles of O = 4 X 0.07 = 0.28

no. of atoms of O = 0.28 x NA = 1.68 X 10 ^23

Answer 2

Answer:

4.7 × 10 to power 22
