We are asked to** identify the element given the mass of the given atoms. **

To solve this we need to** find the molar mass of the element.**

**Recall:**

$\overline{){\mathbf{Molar}}{\mathbf{}}{\mathbf{Mass}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{mass}}{\mathbf{moles}}}$

We go through the following steps to solve this problem:

**Step 1**: Convert the number of molecules to moles (*using the Avogadro’s number*)

**Step 2**: Calculate the molar mass

Identify the element from the following information. In 10.234 grams of this element, there are 1.050 x 10^{23} atoms.

a. H

b. Sc

c. Ni

d. Hf

e. Au
