How many grams are in 0.02 moles of BeI2?

The molar mass of BeI2 (beryllium iodide) is approximately 262.804 g/mol.

To convert moles to grams, you can use the formula:

Mass (g) = moles × molar mass

So, for 0.02 moles of BeI2:

Mass = 0.02 moles × 262.804 g/mol
Mass = 5.25608 grams

Therefore, there are approximately 5.26 grams in 0.02 moles of BeI2.
