## How many moles of CaCl2 are in CaCl2 2h2o?

THe istructions are: Calculate how many moles of CaCl2•2H2O are present in 1.50 g of CaCl2•2H2O and then calculate how many moles of pure CaCl2 are present in the 1.50 g of CaCl2•2H2O.

Initial: CaCl2 x 2H20 (g) 1.50 g
Actual: CaCO3 (g) 1.4 g
% yield

## How many formula units is CaCl2?

So if 1 mole of calcium chloride contains 6.022⋅1023 formula units and has a mass of 110.98 g , you can say that 6.022⋅1023 formula units of calcium chloride have a mass of 110.98 g .

## How many ions are in CaCl2?

In calcium chloride (CaCl2), there are two Cl- ions for each Ca2+ ion. Notice that for ethylene glycol (above) the formula is C2H6O2 and not CH3O (the simplest ratio of C, H and O atoms). 2- ions) and NaOH (Na+ and OH- ions).

## How many fluorine molecules are in one mole of fluorine?

Explanation: Recall that moles can be converted to particles using Avogadro’s constant ( 6.022⋅1023 ) which is the number of molecules per mole of a substance. In 1.5 moles of fluorine gas, there are 1.5⋅6.022⋅1023 molecules of gas.
