A bivalent metal has an equivalent mass of 32 . The molecular mass of the metal nitrate is
- A 182
- B 168
- C 192
- D 188
Answer & Solution
Correct Answer
(D) 188
Step-by-step Solution
Detailed explanation
Atomic mass of the metal \(=32 \times 2=64\)
Formula of metal nitrate \(=\mathrm{M}\left(\mathrm{NO}_{3}\right)_{2}\)
\(\therefore\) Molecular mass \(=64+28+96=188\)
Formula of metal nitrate \(=\mathrm{M}\left(\mathrm{NO}_{3}\right)_{2}\)
\(\therefore\) Molecular mass \(=64+28+96=188\)
