Answer:
32 mols of water
Explanation:
2H2 + O2 ==> 2H2O
What your givens are telling you and what the equation is saying is that
for every mol of O2, you get 2 mols of H2O
So you could do it with the proportion about.
1/16 = 2/x Cross multiply
x = 16 * 2
x = 32

# of atoms per mol = Avogadro’s # (6.022 x 10^23)
Number of mols = mass of substance / molar mass
73 g / 40.08 g = 1.8 mols of Ca in 73 grams
1.8 mols x avagadro’s # = 1.1 x 10^24 atoms in 73 grams of Ca
