Show Work A Sample Is 547g CaCl2 And 5364 G H20 How Many Water Molecules Are Associated With This Hydrate class=

Sagot :

ardni313

The molecular formula of hydrate : CaCl₂.6 H₂O

So there are 6 molecules of H₂O

Further explanation

Given

54.7g CaCl₂ and 53.64 g H₂O

Required

The number of molecules H₂O

Solution

mol CaCl₂ :

= mass : MW

= 54.7 : 111 g/mol

= 0.493

mol H₂O :

= 53.64 : 18 g/mol

= 2.98

mol ratio H₂O : CaCl₂ :

= 2.98/0.493 : 0.493/0.493

= 6 : 1
