Question

write the formulas for the following: 1)find mass when number of moles given 2)find number of moles when mass is given 3)find number of moles when number of particles are given 4)find the number of particles when mass is given

Answer 1

mass=no of mole.atomic weight
no of mole =mass /atomic weight
no of mole=no of particle/avogadro constant
no of particle=avogadro constant(mass/atomic weight)
