Eva8 [605]

Given :

2 Mg + O₂ → 2 MgO

To Find :

How many moles of magnesium oxide are formed if you burn a 2.3 mol sample of magnesium ribbon in the air.

Solution :

From given balanced chemical reaction we can see that 2 mole of Magnesium reacts with 1 mole of O₂ to produce 2 mole of MgO.

A student measured out 0.333 moles of theobromine, CyH3N402 (MM = 180.8/mol) the
Verdich [7]

Answer

2.0 x 10²³ molecules.

Explanation

Given:

The number of moles of theobromide measured out = 0.333 moles.

MM of theobromide = 180.8 g/mol

What to find:

The number of molecules of theobromide the student measured.

To go from moles to molecules, multiply the number of moles by Avogadro's number.

The Avogadro's number = 6.02 x 10²³

1 mole of theobromide contains 6.02 x 10²³ molecules.

So, 0.333 moles of theobromide measured out will have (0.333 x 6.02 x 10²³) = 2.0 x 10²³ molecules.
