Question

the number of ions produced by point 0.1 mole of AlCl3.6H2O in 1 litre solution​

Answer 1

Answer:

2.4088* 10^23 ions

Explanation:

one mole of AlCl3 will dissociate into one mole Al3+ and 3 moles of Cl-. Dissociation Of H2O is very less so we don't consider it's dissociation.

If one mole alcl3 produces Al3+ and 3Cl-. 0.1 mole will produce 0.1 Al3+ and 0.3 Cl-. Total number of ions would be 0.4 mole of ions.

We know 1 mole of ions = avogadro number of ions

so 0.4 mole of ions = 0.4*6.022*10^23 ions

=2.4088*10^23

Answer 2

Answer:

4) 4×6.023×10²²

Explanation:

given : mole(n) =0.1

hence , molecule= 0.1 × 6.023× 10²³

= 0.6023 × 10²³

=6.023 × 10-¹ × 10²³

= 6.023×10²²

Al has +3 charge and Cl has -1 charge there total 4 ion in AlCl36H20 .

Therefore,

total ion = given ion × molecule

= 4 × 6.023 × 10²²
