Answer:
6.2125 g
Explanation:
6.2125 g of Na₂SO₄ is needed to prepare 350 mL of a solution having a sodium ion concentration of 0.125 M.
0.206 moles will contain 0.206 moles x 6.022 × 10^23 atoms which is equivalent to 1.240 x 10^23 atoms.
<h3>Total atoms in a compound</h3>
Given the following parameters
- Mass of Cu2s = 32.8 grams
Get the number of moles
Moles = 32.8/159.16 g/mol
Moles of Cu2S = 0.240moles
Since 1 molecule of atom = 6.02 * 10^23 molecules
Hence 0.206 moles will contain 0.206 moles x 6.022 × 10^23 atoms which is equivalent to 1.240 x 10^23 atoms.

This is generally false.
In a college interview, a student should always ask as many questions as possible <em>(as long as they are relevant to the things being discussed.)</em>
