Question

The number of ions present in 0.2 mole of sodium chloride is

Answer 1

Answer:

0.2

Explanation:

0.2=so^4

0.2=32+16*4

0.2=32+96

0.2=96

no. of moles=0.2/96=0.2

Answer 2

Hi, please consider the answer given below

In the detrmination of the number of bromide ions in 0.2 mole of MgBr2

We use the avogadros number 6.02 x 10^23

Number of molecules of bromide ions= No. of moles x Avogadros number

Number of molecules of bromide ions= 0.2 x (6.02 x 10^23)

= this gives 1.2 x 10^23 bromide ions
