Answer to Question #65427 in General Chemistry for Vanessa Shackelford

Question

If a magnesium atom is 2.0002 times the mass of a carbon atom with 6 protons and 6 neutrons, what is the relative

Answer 1

Solution:
The relative atomic mass element is:
A (relative atomic mass) = p (the number of protons) + n (number of neutrons);
For carbon atom with 6 protons and 6 neutrons relative atomic mass equal to:
A (C) = 6 + 6 = 12 u;
But if the atom of magnesium 2.0002 times the mass of the carbon atom, then:
A (Mg) = A (C) 2.0002 = 24.0024 u
Answer: 24.0024 u
