Chemical Composition of CaCO3

[axel_wong]

Hi all experts

May i know how many percentage of Ca in CaCO3?
Thanks

This one is easy because the molecular mass of CaCO3 is exactly 100.
Ca = 40, C = 12, O3 = 16*3 = 48
So, Ca is 40%.

Other atomic mass can be found in the Periodic Table. See http://ull.chemistry.uakron.edu/peri...ble/index.html

Was thinking of adding CaCO3 but was very expensive.

Please share with me how it goes if you have try it.

Thanks.
