A certain amount of a metal whose equivalent mass is 28 displaces 0.7 L of `H_(2)` at S.T.P. from an acid. Hence, mass of the element is:

A certain amount of a metal whose equivalent weight is 28, displaces 0.7 litre of hydrogen measured at NTP from an acid. Calculate the weight of the metal.

A certain amount of a metal whose equivalent weight is 28, displaces 0.7 litre of hydrogen measured at NTP from an acid. Calculate the weight of the metal.

Calculate the mass of 2.8 litres of CO_(2) at S.T.P.

If 0.5 g of a mixture of two metals. A and B with respective equivalent weights 12 and 9 displace 560 mL of H_(2) at STP from an acid, the composition of the mixture is

If 0.5 g of a mixture of two metals. A and B with respective equivalent weights 12 and 9 displace 560 mL of H_(2) at STP from an acid, the composition of the mixture is

If 0.5g of a mixture of two metals A and B with respective equivalent weights 12 and 9 displace 560ml of H_2 at STP from an acid, the composition of the mixture is

8.34 g of a divalent metal is oxidised by 0.680 L of oxygen (in standard conditions). Hence, atomic mass of the metal is

One mole of chlorine combines with certain weight of a metal giving 111 g of its chloride. The same amount of metal can displace 2 g of hydrogen from an acid. The atomic weight of the metal is:
