Answer: 3 Na atoms in Na3PO4 compound and 1.8066x10^24 atoms of Sodium in 1 molecule of Na3PO4
We are given :
• Sodium phosphate (Na3PO4 )molecule
• Number of Atoms in the Na3PO4 = 3 Na ; 1 P and 4 Oxygen atoms.
This means that Na3PO4 has 3 atoms of Sodium
However ;
• We are to determine how many atoms of sodium (Na) are present in 1 molecule of Na3PO4
,
• Recall that ,1 mole of any substance contains 6.022⋅10^23 ,by avargadros principles.
This means that the number of Sodium atoms in Na3PO4 = 1.8066x10^24 atoms .
