Given Data:
- Mass of metal = 0.5 gm
- Mass of metal oxide = 0.79 gm
Calculation:
- Let the equivalent weight of the metal be x.
- According to the given data, the mass of metal oxide is equal to the sum of the masses of metal and oxygen in the oxide.
- Mass of metal oxide = Mass of metal + Mass of oxygen
- 0.79 gm = 0.5 gm + Mass of oxygen
- Mass of oxygen = 0.79 gm - 0.5 gm = 0.29 gm
Equivalent Weight Calculation:
- Equivalent weight is the weight of a substance that reacts with or replaces 1 gram equivalent of hydrogen.
- The equivalent weight of the metal can be calculated using the formula: Equivalent weight = Atomic weight/Valency
- Since the mass of metal is equal to its equivalent weight, we have:
- Equivalent weight of metal = Mass of metal = 0.5 gm
Atomic Weight Calculation:
- The atomic weight of the metal can be calculated using the formula:
- Atomic weight = Equivalent weight x Valency
- Since the equivalent weight of the metal is 0.5 gm and its valency is 2 (since it forms an oxide), we have:
- Atomic weight = 0.5 gm x 2 = 1 gm/equivalent
Comparing with Known Values:
- The atomic weight of the metal is found to be 1 gm/equivalent.
- From the periodic table, the atomic weight of the metal is 14 (oxygen).
- Therefore, the metal in this case is Oxygen (O) with an atomic weight of 14.
Hence, the equivalent weight of the metal is 14.
- Mass of metal = 0.5 gm
- Mass of metal oxide = 0.79 gm
Calculation:
- Let the equivalent weight of the metal be x.
- According to the given data, the mass of metal oxide is equal to the sum of the masses of metal and oxygen in the oxide.
- Mass of metal oxide = Mass of metal + Mass of oxygen
- 0.79 gm = 0.5 gm + Mass of oxygen
- Mass of oxygen = 0.79 gm - 0.5 gm = 0.29 gm
Equivalent Weight Calculation:
- Equivalent weight is the weight of a substance that reacts with or replaces 1 gram equivalent of hydrogen.
- The equivalent weight of the metal can be calculated using the formula: Equivalent weight = Atomic weight/Valency
- Since the mass of metal is equal to its equivalent weight, we have:
- Equivalent weight of metal = Mass of metal = 0.5 gm
Atomic Weight Calculation:
- The atomic weight of the metal can be calculated using the formula:
- Atomic weight = Equivalent weight x Valency
- Since the equivalent weight of the metal is 0.5 gm and its valency is 2 (since it forms an oxide), we have:
- Atomic weight = 0.5 gm x 2 = 1 gm/equivalent
Comparing with Known Values:
- The atomic weight of the metal is found to be 1 gm/equivalent.
- From the periodic table, the atomic weight of the metal is 14 (oxygen).
- Therefore, the metal in this case is Oxygen (O) with an atomic weight of 14.
Hence, the equivalent weight of the metal is 14.
