Na atoms = (2 moles)(6 x 1023 atoms/mole) = 12 x 1023 ... a) 200g of CaCO3. MW CaCO3 ... 320g of Bromine molecules contains

We know the formula =
n=m/M 
Where,
n = no Of moles 
m= gives mass M= molar mass of that substance 
In this case n =?
m= 200g
M= 
molar mass of Na (sodium)= 22.9897
So, no. Of moles = 200/22.9897 = 8.7 moles
