Answer:
The plant and animal cells are eukaryotic and contain well developed cellular organelles.
The cell membrane, cytoplasm, chromosomes, and mitochondria are the structures that are present in both the plant and the animal cells.
The cell wall and chloroplast are present only in the plant cell.
<u>Given:</u>
Concentration of Na₂S = 0.765 M
Volume of Na₂S solution = 25.0 ml = 0.025 L
Final total volume = 225 ml = 0.225 L
<u>To determine:</u>
The concentration of Na+ ions
<u>Explanation:</u>
# moles of Na₂S = 0.765 * 0.025 = 0.0191 moles
Based on the atomic stoichiometry of Na₂S-
# moles of Na⁺ ions = 2*0.0191 = 0.0382 moles
conc of Na⁺ ions = 0.0382 moles/ 0.225 L = 0.169 M
Ans: [Na⁺] = 0.169 M
