Answer:

615 g

Explanation:

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

  • # moles * Molar mass = grams of substance.

Thus, we now <u>calculate the molar mass of beryllium iodide</u>, BeI₂, using the <em>molar masses of the elements</em>:

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

Finally we <u>calculate how many grams are there in 2.34 moles of BeI₂</u>:

  • 2.34 mol * 262.821 g/mol = 615 g

What are the characteristics of an extrusive rock
olya-2409 [2.1K]

Extrusive Rocks. Igneous rocks which form by the crystallization of magma at the surface of the Earth are called extrusive rocks. They are characterized by fine-grained textures because their rapid cooling at or near the surface did not provide enough time for large crystals to grow.
