A particle<span> is a minute fragment or quantity of matter. In the physical sciences, a </span>particle<span> is a small localized object to which can be ascribed several physical or a</span> chemical<span> properties such as volume or mass.</span>
Molar mass:
O2 = 16 x 2 = 32.0 g/mol Mg = 24 g/mol
<span>2 Mg(s) + O2(g) --->2 MgO(s)
</span>
2 x 24.0 g Mg -------------> 32 g O2
5.00 g Mg -----------------> ( mass of O2)
mass of O2 = 5.00 x 32 / 2 x 24.0
mass of O2 = 160 / 48
= 3.33 g of O2
hope this helps!
