1 one mole of oxygen
2 one gram atom of oxygen
3 \(8 \mathrm{~g}\) of oxygen
4 \({\rm{22}}{\rm{.4 L}}\) of oxygen

330186 On passing \(3 \mathrm{~A}\) of electricity for \(50 \mathrm{~min}, 1.8 \mathrm{~g}\) metal deposits. The equivalent mass of metal is

1 9.3

330187 When a quantity of electricity is passed through \({\rm{CuS}}{{\rm{O}}_{\rm{4}}}\) solution, 0.16 g of copper gets deposited. If the same quantity of electricity is passed through acidulated water, then the volume of \({{\rm{H}}_{\rm{2}}}\) liberated at STP will be [given: at. wt. of Cu = 64]

1 \({\rm{4}}{\rm{.0}}\,\,{\rm{c}}{{\rm{m}}^{\rm{3}}}\)
2 \({\rm{56}}\,\,{\rm{c}}{{\rm{m}}^{\rm{3}}}\)
