Alright, so now we have 7 grams of carbon dioxide and we want to find out how much carbon and oxygen we have. Let's use the same ratio we had before - for every 3 parts carbon, there are 8 parts oxygen in carbon dioxide. That means in total, we have 11 parts making up the carbon dioxide. Since we have 7 grams of carbon dioxide total, we can split that up into those 11 parts. Each part would then weigh 7 divided by 11, which is about 0.64 grams. Now, to find the weight of the carbon, we multiply that 0.64 by the number of carbon parts, which is 3. So, 0.64 times 3 gives us about 1.92 grams of carbon. Finally, to find the oxygen, we multiply the 0.64 by the number of oxygen parts, which is 8. So, 0.64 times 8 gives us about 5.12 grams of oxygen.

Y'all are wrong guys, Sulphur comes with 8 atoms. So, ( Al2 ( SO4 ) 3 ) = 2 + [ ( 8 + 4 ) 3 ] = 2 + (12) (3) = 2 + 36 = 38 hence, Atomicity of aluminium sulphate is 38.
