Answer: 0.39 moles NaPO4
Explanation: Solution: 1 mole of NaPO4 is equal to its molar mass 118g NaPO4
45.8 g NaPO4 X 1 mole NaPO4/ 118 g NaPO4
= 0.39 moles NaPO4
<span>blood is neither acid nor base

it has pH= 7.4</span>
A= liquid core
B= solid core
c= mantle
d= crust

So it should have a lower ionization energy.
Hence we would expect element 2 to be a metal.</span>
