Answer:

Answer below

Explanation:

First to show combustion, you use O₂.

So   C₆H₁₀O₅ +  O₂ is the reaction.  Assuming complete combustion, all you get as products are CO₂ and H₂O.  Then you have to balance the full reaction.

C₆H₁₀O₅  +  6O₂  ----->  6CO₂  +  5H₂O

6 Carbons on each side

10 Hydrogens on each side

What is the formula weight (amu) of the molecule H2O? Use atomic masses of H and O as 1.008 amu and 16.00 amu respectively. Repo
vaieri [72.5K]

Answer:

Formula weight of H₂O molecule is  18.02 amu.

Explanation:

Given data:

Formula weight of H₂O = ?

Atomic mass of H = 1.008 amu

Atomic mass of O = 16.00 amu

Solution:

Formula weight:

"It is the sum of all the atomic weight of atoms present in given formula"

Formula weight of H₂O = 2×1.008 amu + 1×16.00 amu

Formula weight of H₂O = 18.02 amu

Thus, formula weight of H₂O molecule is  18.02 amu.
