Hello!
Please help!

I have to calculate the Ca / P ratio in the hydroxyapatite that I synthesized.
In my hydroxyapatite:
%Ca= 46,63%
%P= 21,31%
How this convert to moles?

Thank you for your help.

I assume the percentages quoted are percentages by mass.
What are the molar masses of Ca and P?
You can adjust the percentages using the ratio of the molar masses
