What does atomic mass do?

The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Prot (MORE)

Does an atom have mass?

Atoms are matter, and all matter has mass. In that light, any (and every) atom has mass. Different atoms of different elements have different masses, as you would expect. As a (MORE)

Why atoms have fractional atomic masses?

Elements can exist as different isotopes, atoms with the same proton number but different neutron number. Their atomic masses are therefore an average, based on the number of (MORE)

Is atomic mass and mass of an atom different?

No, they are not different. The atomic mass number is the average  of the total number of the protons and neutrons in the atom of the  existing isotopes of an element. That' (MORE)

What is the answer to 20c plus 5 equals 5c plus 65?

20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4
