Question

CALCULATE NUMBER MAGNESIUM IONS PRODUCED FROM 0.04 GM OF MAGNESIUM OXIDE?

pls. tellllllll​

Answer 1

Answer:

28g

Explanation:

3 moles of magnesium gives 2 moles of ammonia.

Thus, 3.4 g of ammonia will be formed by

$\frac{3 \times 24 \times 3.4}{34}$

=7.2 g of magnesium.

The amount of magnesium that reacts with oxygen to form MgO is 24−7.2=16.8 g.

The amount of MgO formed is

$\frac{16.8 \times 40}{24}$

=28 g.
