You need to explain it more simple as everyone is clueless
Answer:
The molecular weight will be "28.12 g/mol".
Explanation:
The given values are:
Pressure,
P = 10 atm
= ![10\times 101325 \ Pa](https://tex.z-dn.net/?f=10%5Ctimes%20101325%20%5C%20Pa)
=
Temperature,
T = 298 K
Mass,
m = 11.5 Kg
Volume,
V = 1000 r
= ![1 \ m^3](https://tex.z-dn.net/?f=1%20%5C%20m%5E3)
R = 8.3145 J/mol K
Now,
By using the ideal gas law, we get
⇒ ![PV=nRT](https://tex.z-dn.net/?f=PV%3DnRT)
o,
⇒ ![n=\frac{PV}{RT}](https://tex.z-dn.net/?f=n%3D%5Cfrac%7BPV%7D%7BRT%7D)
By substituting the values, we get
![=\frac{1013250\times 1}{8.3145\times 298}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1013250%5Ctimes%201%7D%7B8.3145%5Ctimes%20298%7D)
![=408.94 \ moles](https://tex.z-dn.net/?f=%3D408.94%20%5C%20moles)
As we know,
⇒ ![Moles(n)=\frac{Mass(m)}{Molecular \ weight(MW)}](https://tex.z-dn.net/?f=Moles%28n%29%3D%5Cfrac%7BMass%28m%29%7D%7BMolecular%20%5C%20weight%28MW%29%7D)
or,
⇒
![=\frac{11.5}{408.94}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B11.5%7D%7B408.94%7D)
![=0.02812 \ Kg/mol](https://tex.z-dn.net/?f=%3D0.02812%20%5C%20Kg%2Fmol)
Answer:
a) 70.29 %
b) 37%
Explanation:
percent reduction can be found from:
PR = 100*(π(do/2)^2-π(df/2)^2)/π(do/2)^2
= 100*(π(11.34/2)^2-π(6.21/2)^2)/π(11.34/2)^2
=70.29 %
percent elongation can be found from:
EL =L_f - Lo/Lo*100
= (73.17 -53.3/53.3)*100
= 37%
