Answer:
approximately 106 grams
Explanation:
The molecular mass of Aluminum Oxide is approximately 102 grams per mole.
2×Al=
2×27=54
3×O=3×16=48
54+48=102
200
102
=1.96 moles
There are two atoms of Aluminum in one mole and each atom has a mass of approximately 27 grams so
Mass of Al = 1.96×2×27=106 grams
Explanation:
it is c because i did this with my teacher and we are doing about chemical atoms
Answer:
mass composition is very essential in obtaining a balanced equation
Explanation:
to have a completely balanced equation that means the right hand side being your reactants must be equal to the right hand side being your product. both sides need to have equal mass composition, when calculating the mass composition make sure both sides are equal if not consider revisiting the number of moles on both sides to ensure they all balance
