Answer
394.23 grams
Explanation
Given:
1.5 moles BeI₂
What to find:
To convert 1.5 moles BeI₂ to grams.
Solution:
The given moles of BeI₂ can be converted to grams using the mole formula below:
[tex]\begin{gathered} Moles=\frac{Mass}{Molar\text{ }mass} \\ \\ \Rightarrow Mass=Moles\times Molar\text{ }mass \end{gathered}[/tex]From the periodic table, atomic masses of: (Be = 9.012, I = 126.904)
So molar mass of BeI₂ = 9.012 + (2 x 126.904) = 9.012 + 253.808
Molar mass of BeI₂ = 262.82 g/mol
Now, plug in moles = 1.5 mol, and molar mass = 262.82 g/mol into the formula:
[tex]\begin{gathered} Mass=1.5\text{ }mol\times262.82\text{ }g\text{/}mol \\ \\ Mass=394.23\text{ }grams \end{gathered}[/tex]Therefore, 1.5 moles BeI₂ to grams = 394.23 grams
