Question

find the number of moles of 2.92 into 10 raise to power 15 atoms of Br2 molecule​

Answer 1

Answer:

Explanation:

Our formula for finding atoms is moles *NA* atomicity so frm this w can calculate moles as

Giev data is

Atoms =2.92*10^15

So moles=atoms/NA*atomicity

2.92*10^15/6.022*10^23*2= 2.4*10^9

Note:here (2) is atomicity as molecules of bromine is 2
