A) 6 M
B) 18 M
C) 10 M
D) 4 M
Correct Answer: B
Solution :
98%\[{{H}_{2}}S{{O}_{4}}\]means 98 g\[{{H}_{2}}S{{O}_{4}}\]in 100 g solution ie, volume of the solution \[=\frac{100}{1.8}mL\] \[=55.55\text{ }mL\] 98 g\[{{H}_{2}}S{{O}_{4}}=1\text{ }mol\] \[\therefore \] \[Molanty=\frac{Moles\text{ }of\text{ }the\text{ }solute}{volume\text{ }of\text{ }solution\text{ }(in\text{ }mL)}\times 1000\] \[=\frac{1}{55.55}\times 1000=18\,M\]
