Thank you for the opportunity to help you with your question!

the mass formula is found from;

Ca x 1 + N x 2 + H x 8 + O x 10

40 x 1 + 14 x 2 + 1 x 8 + 16 x 10 = 236g/mol

Please let me know if you need any clarification. I'm always happy to answer your questions.

Tutor went the extra mile to help me with this essay. Citations were a bit shaky but I appreciated how well he handled APA styles and how ok he was to change them even though I didnt specify. Got a B+ which is believable and acceptable.
