Answer:
[tex]\text{6.12535 }\times10^{21}\text{ atoms}[/tex]Explanation:
Here, we want to get the number of atoms in the given Tungsten mass
Mathematically:
1 mole of Tungsten has a mass of 184g
x moles of Tungsten will have a mass of 1.8722g
Thus:
[tex]\begin{gathered} x\times184\text{ = 1.8722g} \\ x\text{ = }\frac{1.8722}{184}\text{ = 0.010175 mole} \end{gathered}[/tex]1 mole contains 6.02 * 10^23 atoms
0.010175 mole contains x atoms
Thus:
[tex]x\text{ = 0.010175}\times6.02\times10^{23}\text{ = 6.12535 }\times10^{21}\text{ atoms}[/tex]
