Una disolución acuosa de ácido fosfórico H3PO4, (MM = 98,0 [g/mol]) al 85,0% m/m tiene una densidad de 1,71 [g/mL]. A partir de esta información, determine: a) Porcentaje masa – volumen.
b) Concentración molar [mol/L].

the increase of protons   hope this

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
