Which of the following is true about sodium chloride?
- A Molecular mass \(=58.5 \mathrm{amu}\)
- B Formula mass \(=58.5 \mathrm{amu}\)
- C Molecular mass \(=5.85 \mathrm{amu}\)
- D Formula mass \(=5.85 \mathrm{amu}\)
Answer & Solution
Correct Answer
(B) Formula mass \(=58.5 \mathrm{amu}\)
Step-by-step Solution
Detailed explanation
Sodium chloride is an ionic crystal of rock salt structure in which \(4 \mathrm{NaCl}\) units are present in one unit cell of coordination number, \(\mathrm{Na}^{+}: \mathrm{Cl}^{\circ}=6: 6\) So, actual molecule of sodium chloride is not \(\mathrm{NaCl}, \mathrm{NaCl}\) is the…
