<h2>
Answer: 4.94 g </h2>
Explanation:
Mass of solution of Na₃PO₄ = volume × density
= 35.9 mL × 1.10 g/mL
= 39.49 g
Now, since the solution only contains 12.5% Na₃PO₄, then the mass of Na₃PO₄ is 12.5% of 39.49 g
12.5% × 39.49 g = <u>4.94 g </u>
The nucleus of an atom of any element is located at the very center. It contains subatomic particles, proton and neutron. That's why it contains the greater mass, because only the electrons orbit the nucleus. So, you would expect the arrow to point somewhere in the center. A picture of nitrogen's nucleus is shown in the attached picture.
