molecular mass-at.mass of CA+at.mass of Cl2
=12+35.5×2(we take two because after chlorine
we multiply by 2
=12+70.5=82.5
now moles =mass/molecular mass=1/82.5=?
now,1 mole=6.022×10to the ppwer23 molecules
then after dividing 1/82.5=how many molecules
u can do cross multiplication.....thanks
have a nice day....
