A metal oxide is reduced by heating it in a stream of hydrogen. It is found that after complete reduction, 3.15 g of the oxide have yielded 1.05g of the metal. We may deduce that:

1. the atomic mass of the metal is 8

2. the atomic mass of the metal is 4

3. the equivalent mass of the metal is 4

4. the equivalent mass of the metal is 8
