First work out the moles
So do 36g / 80 (80 is bromine's relative Atomic Mass number)
You have 0.45 M
Then, do 0.45 * 6.02*10^23
You get 2.7*10^23, which is your answer

How many atoms are present in helium lithium beryllium boron carbon nitrogen and oxygen?
1 mole of the element has 6.023 x 1023 atoms 1 mole = 4 g of helium = 7 g of lithium = 9 g of beryllium = 11 g of boron = 12 g of carbon = 14 g of nitrogen = 16 g of oxygen
If you have g of beryllium how many moles is this equivalent to?
The formula is: number of moles = g Be/9,012.
