Magnesium is two times heavier than C-12 atom, what shall be the mass of Mg atom in terms of atomic mass unit?

Q.

Magnesium is two times heavier than C-12 atom, what shall be the mass of Mg atom in terms of atomic mass unit?

Q. An atom is $10$ times heavier than $\frac{1}{12}$th of mass of a carbon atom ($C-12$) The mass of the atom in amu is ?

Q. So since 1 atomic unit is exactly 1/12 the mass of 1 c-12 atom,
can we say as follows;
atomic mass of sodium is 23 , so can we say that the atomic mass of sodium is 23 times heavier than 1/12 the mass of 1 carbon-12 atom?

Q. An atom is 10 times heavier than $\frac{1}{{12}^{th}}$ of mass of a C-12 . The mass of the atom in amu is:

Q. Assertion :The atomic mass of potassium is $39u$. Reason: An atom of potassium is $39$ times heavier than $\frac{1}{12}$th of the mass of carbon atom $\left(C^{12}\right)$.
