moles H = 0.3086 H x 1 mol/1 g = 0.3086 moles H
moles P = 3.161 g x 1 mol/31 g = 0.101 moles P
moles O = 6.541 g x 1 mol/16 g = 0.41 moles O
divide all by 0.101 to get 3.0 moles H, 1 mole P and 4 moles O

Is phosphorous acid an element?
The empirical formula for phosphoric acid is H3PO4. Its molecular formula is P2O5·3H2O. It is composed of the elements hydrogen, phosphorus and oxygen. Most solutions of phosphoric acid are composed of some amount of H3PO4 in water, H2O.For more information about phosphoric acid, see the Web Links to the left.
Does phosphoric acid contain phosphate?
It can be called "Hydrogen Phosphate" so in a way i guess but do you mean phosphorus?

How many atoms in the chemical formula h3po4?
There are three hydrogen, one phosphorus and four oxygen atoms in H3PO4. Phosphoric acid is a colourless and odourless liquid.

What is the chemical formula for hydrogen and phosphate?
Phosphorus is symbolised P, Hydrogen is symbolised H
How Many Hydrogen Atoms Are In 3H3PO4?
As 3H3PO4 , there are 9(nine) hydrogen atoms. 3H3PO4 means that there are 3 (three) molecules of phosphoric acid. ; 3H3PO4 = H3PO4 + H3PO4 + H3PO4 However, as one molecule of phosphoric acid, there are only 3 (three) atoms of hydrogen present. The structure of phosphoric acid (as best I can show it is ;_ P(=O) (-OH)3 That is one phosphorus atom double bonded to one oxygen atom, and three hydroxide groups directly bonded to the phosphorus.
A nucleotide contains what elements?
A nucleotide contains the elements carbon, nitrogen, hydrogen, oxygen and phosphorus.

Ch2o
How many atoms of of oxygen does hydrogen phosphide have?
None. Hydrogen phosphide, more commonly called phosphine, contains only hydrogen and phosphorus.
How many atoms in the chemical formula h3po4?
There are three hydrogen, one phosphorus and four oxygen atoms in H3PO4. Phosphoric acid is a colourless and odourless liquid.
Is phosphoric acid organic?
Phosphoric acid contains no carbon and is therefore an inorganic compound.
What are some that contains organic compounds?
carbon, hydrogen, oxygen are the major possibilities carbon hydrogen oxygen nitrogen phosphorus and sulfur
How much phosphoric acid does one ton of calcium carbonate make?
You'd need to produce support for your underlying contention that calcium carbonate can make any phosphoric acid at all. I personally am not seeing it. Calcium carbonate contains neither hydrogen nor phosphorus, both of which are essential for making phosphoric acid. It does contain oxygen (also essential), but it's rather an odd way of obtaining an element that's readily present in the atmosphere.
