3.92 g of ferrous ammonium sulphate crystals are dissolved in 100 mL of water. 20 mL of this solution requires 18 mL of KMnO\(_4\) during titration for complete oxidation. The weight of KMnO\(_4\) present in one liter of solution is :

1 mol He and 3 mol N\(_2\) exert a pressure of 16 atm. Due to a hole in the vessel in which mixture is placed, mixture leaks out. What is the composition of mixture effusing out initially?

In the following reaction, which choice has value twice that of the equivalent weight of the oxidising agent?
\[ \text{SO}_2 + 2\text{H}_2\text{O} \rightarrow \text{S} + 2\text{H}_2\text{O}_2 \]

Three resistors 1 $\Omega$, 2 $\Omega$ and 3 $\Omega$ are connected to form a triangle. Across 3 $\Omega$ resistor a 3 V battery is connected. The current through 3 $\Omega$ resistor is
