By the way it's not mol, it's mole.
The mole is the unit of amount in chemistry. It provides a bridge between the atom and the macroscopic amounts of material that we work with in the laboratory. It allows the chemist to weigh out amounts of two substances, say iron and sulfur, such that equal numbers of atoms of iron and sulfur are obtained. A mole of a substance is defined as:<span>The mass of substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of 12C.</span>
A noble metal is a metal that resists oxidation and does not corrode (i.e: rust). Silver and platinum are great examples since they don't rust
Answer: 16 g of 
reacted with the magnesium
Explanation:
from the equation of reaction: 2Mg + →
48g of Mg requires 32g of O2 to yield 80g of MgO
That is :
48 : 32 : 80
Hence 12 : x: 32
xg of O2 =
= 16 g of
Therefore:
16 g of reacted with the magnesium
