Question

Calculate molarity of cacl2 when it is dissolved in 250 ml solution and gives 3.011*10²³ chloride ions

Answer 1

3.011*10²³ chloride ions= 0.5 moles

vol= 0.25l

molarity = mole/volume(in litres)

= 0.5/0.25

=2 molar

Answer 2

Answer:

Explanation: first you have to calculate the number of moles of chloride ion Cacl2 gives 2 mole of chlorine
