6 electrons. This is Oxygen
<span>For the answer to the question above, we have to use this formula
moles equal mass divided by the molar mass
a) 4.50 g divided by the molar mass of water
molar mass of water = 2x1.0 + 1x16.0 = 18
4.50 g / 18.0 g per mole = 0.25 moles
b) 471.6 g / Molar mass of Ba(OH)2 = moles
c) 129.68 g / molar mass of Fe3(PO4)2 = moles
atoms of P in Mg3(PO4)2
2 atoms of P in each molecule of Mg3(PO4)2
247 g / molar mass of Mg3(PO4)2 = moles
moles of Mg3(PO4)2 x 6.022x10^23 = molecules of Mg3(PO4)2
I hope my answers gave you clarity on your question.</span><span>

Answer is 67.8%
To find the percent yield the equation is actual yield over theoretical yield, and multiply by 100. In this problem it is 4.06996 / 6 = 0.678 x 100 = 67.8%
The answer fam is......... False
NaHCO3 and C8H18 are compounds
