Question

How do you find the atomic mass, because I have to solve this question (below) and I have no clue on how to do it.

Question: An atom has 30 protons, 33 neutrons, and 29 electrons. What is atomic mass?

Answer 1

The atomic mass of an atom is the sum of its protons and neutrons. For an atom with 30 protons and 33 neutrons, the atomic mass is 63 atomic mass units (amu).

Step-by-step explanation:

To calculate the atomic mass of an atom, you need to know the number of protons and neutrons within its nucleus since electrons have a negligible mass. The mass number, which is the sum of protons and neutrons in the nucleus, can be used to determine this atomic mass. In the question provided, the atom has 30 protons and 33 neutrons. To find the atomic mass:

• Add the number of protons (30) to the number of neutrons (33) to get the mass number.
• The mass number is, therefore, 30 protons + 33 neutrons = 63 atomic mass units (amu).

The atomic mass of the given atom is 63 amu.
