Answer:

615 g

Explanation:

In order to convert from moles of any given substance into grams, we have to use said substance's molar mass, as follows:

  • # moles * Molar mass = grams of substance.

Thus, we now calculate the molar mass of beryllium iodide, BeI₂, using the molar masses of the elements:

  • Molar Mass of BeI₂ = Molar Mass of Be + (Molar Mass of I)*2 = 262.821 g/mol

Finally we calculate how many grams are there in 2.34 moles of BeI₂:

  • 2.34 mol * 262.821 g/mol = 615 g
