Answer:One mole of HBr has 6.02 x 1
0
23
 molecules of HBr.
1 mole of HBr = 6.02 x 1
0
23
 molecules of HBr.-----(a)
X mole of HBr has 1.21 x 
10
24
 molecules of HBr.
X mole of HBr = 1.21 x 
10
24
 molecules of HBr------(b)
Taking ratio of (a) and (b)
X / 1 = 1.21 x 
10
24
 / 6.02 x 1
0
23
X= 2.009 moles.
