1.What is the formula for finding percent water hydrates?

2. And what is molecular formula?

It would be better to ask a specific question.

%H2O in a hydrate = [mass H2O/molar mass of hydrate]*100

A molecular formula tells the ratio of the atoms to each other in a compound. For example, in H2O, there are two H atoms to 1 O atom. This happens to be the empirical formula as well as the molecular formula. The molecular formula is some whole number times the empirical formula. In the case of H2O, the whole number is 1.0.

thank you!

1. To find the percent water in hydrates, you need to determine the mole ratio between water molecules and the anhydrous substance (the non-water part) of the hydrate. The formula to calculate the percent water in hydrates is:

Percent Water = (Number of moles of water / Number of moles of hydrate) × 100

To obtain the number of moles of water, you can multiply the molar mass of water (18 g/mol) by the number of water molecules present in the hydrate. To obtain the number of moles of the hydrate, you can multiply the molar mass of the hydrate by the mass of the hydrate sample.

2. The molecular formula represents the actual number of atoms of each element that make up a molecule. It provides the composition and structure of a compound. For example, the molecular formula for water is H2O, where H represents hydrogen and O represents oxygen. The subscript numbers indicate the number of atoms of each element in the molecule.

In general, the molecular formula gives the exact number of atoms present in a molecule, providing a more detailed description of the compound compared to its empirical formula, which only indicates the relative ratios of elements within the molecule.
