Question

Need help in this I don’t understand what the mass would be so confusing there are no labels to this exercise

Answer 1

`10\text{ a.m.u}`

Step-by-step explanation:

Here, we want to get the mass of the given atom

The atomic mass is simply the sum of the mass of the protons and neutrons

From the nucleus, we can see that we have 5 protons and 5 neutrons

Although they have different charges, they have roughly the same mass

The mass of each is approximately equal to 1

Thus, we have the mass of the atom as;

`5(1)\text{ + 5(1) = 10 a.m.u}`
