Question

Calculate the number of K ions in 3 mole of k2o

Answer 1

Answer:  3.6132 x 10^24   K+ ions

Explanation: We have 3 mole of K20

In 1 mole of K2O , there would have been 2 moles of K+ ions

So in 3 moles of K2O ,

There would be 3 x 2 , i.e. , 6 moles of K+ ions .

Since 1 mole = 6.022 x 10^23

6 moles will be = 6 x 6.022 x 10^23 ions

                          = 36.132 x 10^23 ions

                          = 3.6132 x 10^24   K+ ions

Thus , this is the answer .
