~Solution :-

  • Here, to find the atomic mass of element, we must;

We know that,

  • 4.6 x $ \sf{10^{22}}$ atoms of an element weigh 13.8g.

Thus,

The atoms of $ \sf{ 6.02 \times 10^{13}}$ will weigh;

[tex] = \sf{\frac{13.8 \times 6.02 \times {10}^{23} }{4.6 \times {10}^{22} } } \\ [/tex]

[tex] = \sf{180.6 \: g \: \: (molar \: mass)}[/tex]

  • Hence, the molar mass (atomic mass) will be 180.6 g.
