In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.
According to the kinetic theory of matter, the molecules that compose matter are in constant random motion. The nature of this motion varies in the three states of matter which are;
In the solid state, the molecules do not translate, they only vibrate and rotate about their mean positions. In the liquids state, the molecules translate but they still have restricted degrees of freedom due to intermolecular interactions. In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

4X + 3O₂ = 2X₂O₃
n(X₂O₃)=0.02225 mol
m(X)=4.000 g
x - the molar mass of metal
m(X)/4x=n(X₂O₃)/2
x=m(X)/{2n(X₂O₃)}
x=4.000/{2*0.02225)=89.89 g/mol
X=Y (yttrium)
Answer:
.........................................
Explanation:
I’m assuming the top ruler has more measurement points, like more specific numbers. This would mean the top ruler is more reliable because you can be more specific with your measurements
