Answer:
135.027
Explanation:
Take the molar mass (from the periodic table) of Nitrogen (14.007) and Oxygen (15.999)
Add them together: 30.006 (this is 1 mole of NO)
30.006x4.5=135.027g
Answer:
Isotopes
Explanation:
This is the definition of isotopes: they are atoms of the same element that contain different numbers of neutrons.
Answer:
0.50 M is the molar concentration of
.
Explanation:
The equilibrium constant of the reaction = 

Equilibrium concentration of
= 0.050 M
![[NO_2]=0.050 M](https://tex.z-dn.net/?f=%5BNO_2%5D%3D0.050%20M)
Equilibrium concentration of
= ?
![[N_2O_4]= x](https://tex.z-dn.net/?f=%5BN_2O_4%5D%3D%20x)
The equilibrium constant of the reaction is given aSL:
![K_c=\frac{[NO_2]^2}{[N_2O_4]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO_2%5D%5E2%7D%7B%5BN_2O_4%5D%7D)


0.50 M is the molar concentration of
.
On the cumulative Report, it would be much easier to read for the patients if the ranges in parentheses were tabbed over from the actual result instead of printing directly one space after the result.
