Question

Convert the following moles to grams 1.5 moles BeI2

Answer 1

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:

$\begin{gathered} Moles=\frac{Mass}{Molar\text{ }mass} \\ \\ \Rightarrow Mass=Moles\times Molar\text{ }mass \end{gathered}$

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:

$\begin{gathered} Mass=1.5\text{ }mol\times262.82\text{ }g\text{/}mol \\ \\ Mass=394.23\text{ }grams \end{gathered}$

Therefore, 1.5 moles BeI₂ to grams = 394.23 grams
