Answer:  Holmium-165 = Er-165 + electron

Explanation:

Beta decay is the decay of a neutron into a proton and electron.  This will increase the number of protons in the Holmium nucleus by one, making it Er, Erbium, with the same atomic mass.  

Holmium-165 = Er-165 + electron

The mass is essentially the same, as the proton is assigned the same mass as the neutron it came from.

What is the mass, in grams, of 122 atoms of aluminum? Round your answer to proper significant figures.
tangare [24]

Answer:

Mass = 547.02 × 10⁻²³g

Explanation:

Given data:

Number of atoms of Al = 122 atom

Mass in gram = ?

Solution:

Avogadro number:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ atoms

122 atom/6.022 × 10²³ atoms ×  1 mol

20.26× 10⁻²³ mol

Mass in gram:

Mass = number of moles  × molar mass

Mass = 20.26× 10⁻²³ mol  × 27 g/mol

Mass = 547.02 × 10⁻²³g
