A) \[1.8\]
B) \[48.4\]
C) \[91.8\]
D) \[94.6\]
Correct Answer: C
Solution :
The density of solution\[=1.8\,g\,\,ml\] Weight of one litre of solution\[=1800\,\,g\] \[\therefore \]weight of \[{{H}_{2}}S{{O}_{4}}\] in the solution \[=\frac{1800\times 90}{100}\] \[=1620\,\,g\] \[\therefore \]weight of solvent\[=1800-1620\] \[=180\,\,gm\] \[\therefore \]molality\[=\frac{1620}{98}\times \frac{100}{180}=91.8\]You need to login to perform this action.
