A \(1.17 \%\) solution of solute \(A\) is isotonic with \(7.2 \%\) solution of glucose. If the molecular weight of solute \(A\) is 58.5, the value of van't Hoff factor, ' \(i\) ' is
- A 2
- B 3
- C 4
- D 5
Answer & Solution
Correct Answer
(A) 2
Step-by-step Solution
Detailed explanation
\(\because\) Molar mass of glucose \((M)=180 \mathrm{~g}\) Molar mass of solute \((A)\), i.e. \(\left(M_A\right)=58.5\) \(\%\) of \(A=1.17 \%\) \(\%\) of glucose \(=7.2 \%\) Also, \(\because \pi(\text { osmotic pressure })=C R T\)…
