Answer:
49.2 g/mol
Explanation:
Let's first take account of what we have and convert them into the correct units.
Volume= 236 mL x (
) = .236 L
Pressure= 740 mm Hg x (
)= 0.97 atm
Temperature= 22C + 273= 295 K
mass= 0.443 g
Molar mass is in grams per mole, or MM=
or MM=
. They're all the same.
We have mass (0.443 g) we just need moles. We can find moles with the ideal gas constant PV=nRT. We want to solve for n, so we'll rearrange it to be
n=
, where R (constant)= 0.082 L atm mol-1 K-1
Let's plug in what we know.
n=![\frac{(0.97 atm)(0.236 L)}{(0.082)(295K)}](https://tex.z-dn.net/?f=%5Cfrac%7B%280.97%20atm%29%280.236%20L%29%7D%7B%280.082%29%28295K%29%7D)
n= 0.009 mol
Let's look back at MM=
and plug in what we know.
MM= ![\frac{0.443 g}{0.009 mol}](https://tex.z-dn.net/?f=%5Cfrac%7B0.443%20g%7D%7B0.009%20mol%7D)
MM= 49.2 g/mol
Answer:
![NO \longrightarrow N_2O_2 \longrightarrow N_2O \longrightarrow N2](https://tex.z-dn.net/?f=NO%20%5Clongrightarrow%20N_2O_2%20%5Clongrightarrow%20N_2O%20%5Clongrightarrow%20N2)
Explanation:
The intermediates are the products of all the steps of the reaction pathway, with the exception of the last one. So the intermediates will be:
- N2O2 from the first step
- N2O from the second step
The list from reactant to final product:
![NO \longrightarrow N_2O_2 \longrightarrow N_2O \longrightarrow N2](https://tex.z-dn.net/?f=NO%20%5Clongrightarrow%20N_2O_2%20%5Clongrightarrow%20N_2O%20%5Clongrightarrow%20N2)
<em>Note: the water is considered a by-product, given that is not the product of interest in this steps.</em>
