Answer : Molar mass of the
is 159.7 g/mol.
Molar mass of the
is 101.96 g/mol.
Explanation:
Molar mass of
:
![\text{Atomic mass of Fe}\times 2+\text{Atomic mass of O}\times 3](https://tex.z-dn.net/?f=%5Ctext%7BAtomic%20mass%20of%20Fe%7D%5Ctimes%202%2B%5Ctext%7BAtomic%20mass%20of%20O%7D%5Ctimes%203)
Molar mass = ![55.85 g/mol\times 2+16.00 g/mol\times 3=159.7 g/mol](https://tex.z-dn.net/?f=55.85%20g%2Fmol%5Ctimes%202%2B16.00%20g%2Fmol%5Ctimes%203%3D159.7%20g%2Fmol)
Molar mass of the
is 159.7 g/mol
Molar mass of
:
![\text{Atomic mass of Al}\times 2+\text{Atomic mass of O}\times 3](https://tex.z-dn.net/?f=%5Ctext%7BAtomic%20mass%20of%20Al%7D%5Ctimes%202%2B%5Ctext%7BAtomic%20mass%20of%20O%7D%5Ctimes%203)
Molar mass = ![26.98 g/mol\times 2+16.00 g/mol\times 3=101.96 g/mol](https://tex.z-dn.net/?f=26.98%20g%2Fmol%5Ctimes%202%2B16.00%20g%2Fmol%5Ctimes%203%3D101.96%20g%2Fmol)
Molar mass of the
is 101.96 g/mol
Answer:
= 18.75 L
Explanation:
Using the combined gas law;
P1V1/T2=P2V2/T2
Where; P1 is the initial pressure, 0.25 atm
V1 is the initial volume 300.0 L
T1 is the initial temperature, 400 K
P2 is 2 atm and
T2 is 200 K
Therefore;
(0.25 × 300)/400 = 2V2/200
V2 = (75 ×200)/(400×2)
= 18.75 L
Answer:
Explanation:
The Erosion in the Colorado Rookies Scenario that record a ready rain were more than the other scenario in the same area with just a drizzle. The Erosion is much in the Colorado Rockies Scenario that record a steady rain because the volume of the rivers has goes up compare to that of the Scenario with just a drizzle. As a result of the increased in the amount of the rivers bank that is flowing, the river flows more faster which helps in the transportation of the sediments or Erodes.
