Question:

A metal y forms two oxides u and v. 0.75g of u and v contain 0.18g and 0.27g of oxygen respectively. Calculate the masses of metals in grams. Calculate the masses of metals that combine with a gram of oxygen in each case.

Metals and their oxides

Metals can combine with oxygen in different ratios by mass to form different oxides where the metals differ in the oxidation states. Some oxides might also result from a mixture of two different oxidation states of the metal in a single compound. A classic example of such different oxides of a metal is the oxides of iron. {eq}Fe_2O_3 \ and \ Fe_3O_4{/eq} are two common oxides of iron. {eq}Fe_3O_4{/eq} is a compound containing both {eq}Fe_2O_3 \ and \ FeO{/eq}.

  • Given,mass of metal oxide u = 0.75 g

Mass of oxygen in oxide u = 0.18 g

Therefore mass of metal y in u = 0.75 g - 0.18 g = 0.57 g

  • Given,mass of...
