Ice is constantly subliming to form a layer of water vapor
The number of grams of Magnesium oxide= 106 g
<h3>Further explanation</h3>
Given
2.63 moles of Magnesium oxide
Required
mass of Magnesium oxide
Solution
The mole is the number of particles contained in a substance
<em>
1 mol = 6.02.10²³
</em>
Moles can also be determined from the amount of substance mass and its molar mass
Mol = mass : Molar mass
Mass of Magnesium oxide(MgO, MW=40.304 g/mol) :
= mol x MW
= 2.63 x 40.304
= 106 g
