Use the state equation for ideal gases: pV = nRT
Data:
V = 88.89 liter
n = 17 mol
T = 67 + 273.15 = 340.15 K
R = 0.0821 atm * liter / (K*mol)
=> p = nRT / V = 17 mol * 0.0821 (atm*liter / K*mol) * 340.15 K / 88.89 liter
p = 5.34 atm
Answer: p = 5.34 atm
<span>The gaseous mixture contains 414.0 torr of h2(g), 345.7 torr of n2(g), and 80.1 torr of ar(g). Then, total pressure of the gas would be: 414 torr + 345.7 torr + 80.1 torr= 839.8 torr
The mole fraction of each gas:
H2= 414 torr/</span>839.8 torr= 0.49
N2= 345.7 torr/839.8 torr= 0.41
Ar= 80.1 torr/839.8 torr= 0.10
True would be your answer
Hydrogen. The three most common organic compounds are hydrogen, oxygen, and nitrogen.
<span>Fe atomic mass = 55.86
* 1 = 55.86
Cr atomic mass = 52
*2 = 104
O atomic mass = 16
* 4 = 64
Total molecular mass = 223.86
Percent by mass Fe = (55.86/223.86)*100 = 24.95%
Percent by mass Cr = 46.45%
Percent by mass O = 28.59%</span>
