Are my answers correct, did i do it right?
N2 converted is 0.874molN2 and O2 is 0.875molO2
mols N2=24.5g/28.01=0.8747 which rounds to 0.875 & mols O2 = 28.0/32=0.875
N2: P=? PV=nRT
V=5.ool PV/V=nRT/V
n=0.874molN2 P=nRT/V ok to here.
R=0.21latm/molk With P in atm and T in K, R=0.08206 L*atm/mol*K so you need to redo this. I assume you did the same kind of thing for pO2
T=298k
P=0.874+0.821+298/5.00=299.695/5.oo= oo is the letter o. 00 are the numbers.
59.9392 Even if you had used the correct value for R, the + signs I have highlighted in the equatiion should be multiplied and not added. Here is the way it should look.
PN2=?

P*5.00=0.875*0.08206*298.
Solve for P=4.28 atm.
I will let you do the remainder.

Read this post and not the other one. I forget to remove some of the bold faced type. I will try to get this one right.
