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

The standard conditions for G^0 are ____

4 g of a metal oxide contains 1.6 g-oxygen, then equivalent mass of the metal is

4 g of a metal oxide contains 1.6 g-oxygen, then equivalent mass of the metal is

A metal oxide has the formula Z_(2)O_(3) . It can be reduced by hydrogen to give free metal and water. 0.1596 g of the metal requires 6 mg of hydrogen for complete reduction. The atomic mass of the metal is:

Same amount of metal combines with 0.1g of oxygen and lg of a halogen. Hence the equivalent mass of halogen is :

The same amount of a metal combines with 0.20 g of oxygen and with 3.17 g of a halogen. Hence equivalent mass of halogen is
