What is the percent composition of phosphoric acid H3PO4
Agata [3.3K]
Hey there!:

Molar mass H3PO4 = <span>97.9952 g/mol

Atomic Masses :

H = </span><span>1.00794 a.m.u

</span>P = <span>30.973762 a.m.u

</span>O =  15.9994 a.m.u<span>

H % =  [ ( 1.00794 * 3 ) / </span> 97.9952  ]  * 100

H% = <span>3.0857 %

P % = [ ( </span>30.973762 * 1 ) / 97.9952 ] * 100

P% = <span>31.6074 %

O % = [ ( </span>15.9994 * 4 ) / 97.9952 ] * 100

O% = <span>65.3069 %


Hope this helps!</span>

quizlet nitrogen can have variable number of nuetrons(isotopes) it can also have varible number of electrons ehile becomon an io
mafiozo [28]

Nitrogen has 7 protons, 7 neutrons, and 7 electrons.

Seven protons, seven neutrons, and seven electrons make up nitrogen-14.

Utilize the atomic number and mass number of an atom to determine the number of subatomic particles it contains: Atomic number Equals proton count. Electron count equals atomic number. Atomic number - mass number equals the number of neutrons.

Seven protons, seven neutrons, and seven electrons make up the atom of nitrogen. The nucleus is the collection of protons and neutrons that make up the center of an atom. The 7 electrons, which are much smaller than the nucleus, orbit it in what is known as orbits. Since nitrogen-14 is a neutral atom, the number of protons in its nucleus must match the number of electrons around it.
