Step 1:
I'll solve this problem step by step, following the precise LaTeX formatting guidelines:

Step 2:
: Understand the Given Information

- We know that the mass of an atom of element x is equal to the mass of 7 hydrogen atoms - This means we need to calculate the mass of 7 hydrogen atoms

Step 3:
: Recall the Mass of a Hydrogen Atom

- The mass of a single hydrogen atom is approximately $$1.67 \times 10^{-27} \mathrm{kg}

Step 4:
: Calculate the Total Mass of 7 Hydrogen Atoms

- $$m_{x} = 11.69 \times 10^{-27} \mathrm{kg}
- Mass of element x = 7 × mass of hydrogen atom

Final Answer

The mass of the atom of element x is 11.69 \times 10^{- 27} \mathrm{kg}, which is equivalent to the total mass of 7 hydrogen atoms.
