Formula of sodium phosphate = Na₃PO₄
So, one mole of sodium phosphate molecules have 3 moles of Na atoms
Then, 1.6 moles of Na₃PO₄ will have: 1.6 × 3 = 4.8 moles of sodium atoms will be present
There isn't any molecules in plasma, hope this helps
From the information provided in the question, the mass of gold that can be obtained from this sample is 31.5 g of Au.
Given that the reduction of gold III occurs thus;
Au^3+(aq) + 3e ------> Au(s)
Number of moles of gold(III) chloride dihydrate = mass/molar mass = 54.9 g /339.35 g/mol = 0.16 moles
Number of moles of Au^3+ in AuCl3.2H20 = 0.16 moles
Now;
1 mole of Au has a mass of 197 g/mol
0.16 moles of Au has a mass of 0.16 moles × 197 g/mol/1 mole
= 31.5 g of Au.
The mass of gold that can be obtained from this sample is 31.5 g of Au.
