What is the mass ratio of 2molo3 to 3molo2? What is the ratio of the number of molecules? What is the ratio of the number of oxygen atoms? At the same temperature and pressure, what is the ratio of the number of CO and CO2 molecules in the same volume? What is the ratio of the number of atoms? What is the mass ratio?

Mass ratio of O2 to O3 1:1
Molecular ratio 2:3
Oxygen atom number 1:1
Molecular number of CO and CO2 1:1
Atomic number 2:3
Mass ratio 7:11
If the amount of matter is equal, that is, the number of molecules is equal. Just remember this

What determines the relative atomic mass of an atom

Sum of protons and neutrons

The relative atomic mass of an atom depends on the atomic structure 1. Proton number 2, neutron number 3, outermost electron number 4, atomic nucleus

1. Proton number 2, neutron number

Atomic structure and relative atomic mass 1. If the mass of one atom of the element is W G, the relative atomic mass of the atom is __ If the relative molecular mass of a molecule is a, the actual mass of the molecule is _ 2. Neutralize 0.68 dibasic acid H2X to become normal salt, and 0.04 mol NaOH solution is consumed, so the molar mass of H2X is ___, The relative atomic mass of X is_____

1.W*NA
A/NA
two point three four
thirty-two

In atoms, what determines the relative atomic mass is ()

Number of protons and neutrons,
Or nucleus

Senior one chemistry -- about the approximate relative atomic mass of atoms Description of 24 (upper left corner) 12 (lower left corner) mg "the approximate relative atomic mass of 24 (upper left corner) 12 (lower left corner) mg atom is 24", right? Why?

What does this question mean?
It is wrong to say that the 24 in the upper left corner of Mg is called the approximate relative atomic mass, because this 24 is called the mass number
However, the approximate relative atomic mass of Mg is indeed 24. They are the same in value, but the meaning and calculation method are different
I don't know if you understand
