The forward and reverse reactions proceed at the same rate once at equilibrium.
Answer:
Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen's is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; that is, 2(1) + 1(16) = 18 grams/mole.

Answer:
Explanation:
Since no information was provided about the can of soda, let's take an example of 1 can of 12 fl oz (368 g) Coca-Cola.
The nutrition facts state that it contains 33 g of sugar. In order to calculate the number of molecules, we firstly need to know the molecular formula of sugar. Sugar can be represented by .
Our first step is to find the molar mass of sugar:
Secondly, dividing mass of sugar, , by the molar mass will yield the number of moles of sugar:
Finally, multiplying moles by the Avogadro's constant will yield the number of molecules:
