Answer:
1.8 x 10^24
One mole of helium has 6.02 x 10^23 atoms, thise number is also called Avogadro's number or constant.
If we need number of atoms for 3 moles so simply, multiply 3 by 6.02 x 10^23
so,
Number of atoms for 3 moles = 3 x ()
Number of atoms will be = 1.806x10^24
the volume of 2.5% m/v koh which can prepared from 125 ml of a 5% koh solution is calculated using the following formula
m1v1= m2 v2
M1= 5/100= 0.05
v1= 125
m2=2.5/100=0.025
V2=?
v2= m1v1/m2
=0.05 x125 /0.025=250 ml
