What is the by mass of water in the hydrate CoCl2 * 6H2O?

237.95 g/mol
The molar mass of CoCl2 is 129.83 g/mol The molar mass of H2O is 18.02 g/mol and the molar mass of 6H2O is (6)( 18.02 g/mol) = 108.12 g/mol The molar mass of CoCl2∙6H2O is 237.95 g/mol (The 6 in front of the H2O needs to be taken into account!)

How do you calculate the percent of water in a hydrate?

Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical (actual) percent hydration (percent water) can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.

Is CoCl2 a hydrate?

Cobalt(II) chloride is an inorganic compound of cobalt and chlorine, with the formula CoCl2. The compound forms several hydrates CoCl2•nH2O, for n = 1, 2, 6, and 9. Claims of the formation of tri- and tetrahydrates have not been confirmed.

What is the percentage of water in the hydrate CoCl2 6H 2 O show your work?

1 Expert Answer

11.3 g H2O/25.0 grams hydrate (x100%) = 45.2% water by weight. This happens to be the % water of the normal hydrate, CoCl2•6H2O.

What is the formula of the hydrate?

Formula of a Hydrate (Anhydrous Solid⋅xH2O)

In order to determine the formula of the hydrate, [Anhydrous Solid⋅xH2O], the number of moles of water per mole of anhydrous solid (x) will be calculated by dividing the number of moles of water by the number of moles of the anhydrous solid (Equation 2.12.

What is the percent by mass of water in the hydrate?

The percent by mass of water in a hydrate can be calculated by dividing the mass of H2O in 1 mole of the hydrate by the molar mass of the hydrate and then multiplying by 100%.

How many molecules are there in 450g of Na2SO4?

Divide 450 grams by the molecular mass, 142. You’ll get approximately 3.16 moles of Na2SO4 in 450 grams. Now you multiply that with 855.124*10^23 to get 2702.19*10^23molecules.
