Sagot :
Answer:
B 64
Explanation:
i think b 64 is right answer.......
The relative atomic mass is 64g and the metal is copper(Cu).
What is relative atomic mass?
- The weighted average of the masses of an element’s isotopes in comparison to the mass of a carbon-12 atom is known as relative atomic mass (Ar).
- The ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant is defined as relative atomic mass (Ar) or atomic weight.
The mole ratio for M and O in the compound MO is 1:1.
The mass of oxygen in the 16g compound is 16.0 - 12.8 = 3.2g.
The relative atomic mass of O is 16g. The number of moles of O in the 3.2g is 3.2/16 = 0.2.
Since the M and O gave the same number of moles in the MO, that is their mole ratio is 1:1, then the number of moles of the M in the MO is also 0.2.
Therefore, if 0.2 mole if M weighs 12.8g, then 1 mole of M will weigh 1 x 12.8/0.2 = 64g/mole.
The mole of an element is its relative atomic mass.
Therefore, the relative atomic mass of M is 64g.
Hence, option B is the correct answer.
