Question

calculate the number of ions obtained from cacl2 when 222 g of it is dissolved in water

Answer 1

$3.6132 \times {10}^{24} number \: of \: ions \: are \: there$

thats the answerrr

Answer 2

Answer:

Explanation:

1 mole→ 111 g CaCl  

2

​

 

∴ 222gCaCl  

2

​

 is equivalent to 2 moles of CaCl  

2

​

 

Since 1 formula unit CaCl  

2

​

 gives 3 ions, therefore, 1 mol of CaCl  

2

​

 

will give 3 moles of ions

2 moles of CaCl  

2

​

 would give 3×2=6 moles of ions.

No. of ions = No. of moles of ions × Avogadro number

=6×6.022×10  

23

 

=36.132×10  ^23

 

=3.6132×10 ^24  ions
