A polymer contains 50 molecules with molecular mass 5000, 100 molecules with molecular mass 10,000 and 50 molecules with molecular mass 15,000. Calculate number average molecular mass?
- A 5,000
- B 75,000
- C 10,000
- D 20,000
Answer & Solution
Correct Answer
(C) 10,000
Step-by-step Solution
Detailed explanation
\(\because\) Number average molecular mass \((M n)\) \[ =\frac{N_2 M_2+N_2 M_2+N_3 M_3}{N_2+N_2+N_3} \] where, \(N_2, N_2\) and \(N_3\) are number of molecules and \(M_2, M_2\) and \(M_3\) are respectively their molecular masses. Given,…
