### How to find the percent of water in a hydrate?

1. Find the molar mass of the hydrate. Find the molar mass of the water molecules (18.01528 x # water molecules) and of the anhydrate; add the values together to find the molar mass of the hydrate. Molar Mass Water + Molar Mass Anhydrate = Molar Mass Hydrate 2. Find the percent of water in hydrate. Divide the molar mass of water by the molar mass of hydrate; multiply by 100%. - Mass water Mass…

### What is the theoretical percentage of water of hydration in cacl2-2h20?

1. Find the molar mass of the hydrate (Calcium Chloride Dihydrate). Find the molar mass of water and the anhydrate (anhydrate + water = hydrate); add the molar mass values of each to find the molar mass of the hydrate. Molar Mass CaCl2: 110.98g + Molar Mass H2O: 36.04g* Molar Mass CaCl2 * 2H2O: 147.01g Finding Molar Mass # atoms element A * atomic mass element A = Mass A # atoms element B *…

### Mass of a mole?

The molar mass of an element is its atomic weight in grams. The molar mass of a molecule or compound is the sum of the subscripts times the molar masses in grams. For example, the molar mass of hydrogen, H, is 1.00794g and the molar mass of oxygen, O, is 15.9994g. The molar mass of water, H2O, is (2 x 1.00794g) + (1 x 15.9994g O) = 18.01528g.

### How do you convert the mass of a substance to the number of moles in a substance?

You must first calculate the molar mass of the substance. To do so, you add up the molar masses of all the elements that make up the compound, multiplied by the number of atoms of that element in one molecule of the substance. For example, AgNO3 has a molar mass of about 169.8 amu. In one molecule of AgNo3, there is one atom of Silver (molar mass 107.8), one atom of Nitrogen (molar mass 14)…

### What is the molar mass of potassium hydroxide?

molar mass is the mass of one mole of a substance. A mole is an amount, refers to Avogadros number which is 6.022 x 1023. a mole of atoms is that many atoms. therefore the molar mass of potassium hydroxide KOH is the mass of that many molecules of KOH. On the periodic table the mass number for each element is molar, so all you need to do is add together the molar mass of…
