Given:
2.5 mol O2
Required:
Grams of water
Solution:
2H2 + O2 -> 2H2O
Moles of H2O = (2.5 mol O2)(2
moles H2O/1 mole O2) = 5 moles H2O
Molar mass of H2O = 18.02 g/mol
Mass of H2O = (5 moles H2O)( 18.02
g/mol)
Mass of H2O =90.1g H2O
Answer:
1033.36g
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 molecules. This means that 1 mole of SO2 also contains 6.02x10^23 molecules.
1 mole SO2 = 32 + (16x2) = 64g.
Now, If 64g of SO2 contains 6.02x10^23 molecules,
Therefore, Xg of SO2 will contain 9.72x10^24 i.e
Xg of SO2 = (64x9.72x10^24)/6.02x10^23
Xg of SO3 = 1033.36g.
Therefore, 1033.36g of SO2 contains 9.72x10^24 molecules
