Stoichiometry:
First, calculate the number of grams for one mole of Ca3 (PO3)4
(3 * (Mass of Ca)) + (4 * (Mass of P + (3 * Mass of Oxygen)))
= (3*40.08) + 4(30.97 + (3*16.00))
=(120.24) + 4(78.97)
=436.12 g / mol Ca3(PO3)4
This means there are 436.12 g per 1 mole of Ca(PO3)4. Since there are 4.50 moles of Calcium Phosphate, mulitply the molar mass of Ca(PO3)4 by 4.50 and you should get 1962.54 g. Since there are 3 sigfigs, the final answer is 1960 g.
on a side note: I put in all my work in case 1. your periodic table if different, 2. my work is wrong, 3. you put in the question wrong because I feel that the actual compound would be Ca3(PO4)3 instead of Ca3(PO3)4 (if this is the case, the answer should be 1820 g).
Answer:
its a option neutralization takes place between acid and base plz mark me branliest
<span>Question: Organic chemistry is the study of compounds containing?
Answer: (A) Carbon
Organic chemistry is the study of compounds that contain the element carbon, or the study of carbon-containing molecules and the compounds they form. An entire branch of chemistry (carbon chemistry) is dedicated to this subject. Which means carbon is quite important, after all it is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and Organic compounds together scientists can learn more about life, the human body, and how it works!</span>
When solid surfaces slide over each other, the kind of friction that occurs is called <u>Sliding Friction.</u>
