Question

8) Find the mass of neutron in a.m.u (Mn = 1840 mass of Me)
​

Answer 1

Step-by-step explanation:

The mass of a neutron is approximately 1 atomic mass unit (a.m.u). To find the mass of a neutron in a.m.u, we need to know the mass of an electron (Me) and the mass number of a neutron (Mn).

Given that the mass of a neutron (Mn) is 1840 times the mass of an electron (Me), we can calculate the mass of a neutron in a.m.u by dividing Mn by Me.

Mass of neutron = Mn / Me

Since the mass of an electron is very small compared to the mass of a neutron, we can ignore the decimal places in the mass of an electron.

Therefore, the mass of a neutron in a.m.u is approximately 1840.

In summary, the mass of a neutron in a.m.u is approximately 1840

Answer 2

The mass of a neutron is approximately 1.00756 atomic mass units, derived from the fact that it is roughly 1840 times the mass of an electron (0.0005486 a.m.u).

The neutron is a subatomic particle found in the nucleus of an atom, and its mass is commonly expressed in atomic mass units (a.m.u). To find the mass of a neutron in a.m.u, you can use the fact that the mass of a neutron is approximately 1840 times the mass of an electron (Me). The mass of an electron is about 0.0005486 a.m.u.

Mass of neutron (Mn) = 1840 * Mass of electron (Me)

Mass of neutron (Mn) = 1840 * 0.0005486 a.m.u

Calculating this, you get:

Mass of neutron (Mn) ≈ 1.00756 a.m.u

Therefore, the mass of a neutron is approximately 1.00756 atomic mass units. This value represents the average mass of neutrons in atomic nuclei and is commonly used in nuclear physics and chemistry.
