Answer:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
Explanation:
Mole percentage of nitrogen gas = 25 mole%
Mole percentage of hydrogen gas = 75 mole%
Average molecular weight of the mixture:
Rate of flow of the stream = 3000 kg/h
Mass of stream in 1 hour = 3000 kg = 3,000,000 g
Moles of stream :
Moles of nitrogen gas in 352,941.17 moles of stream be x
x = 88,235.294 mol
Mass of 8,823,529.4 mole of nitrogen gas:
The rate of flow of nitrogen into the reactor is 2,470.588 kg/h.
It’s the first 1 M yea it’s the first one
Explanation:
As we know that density is the amount of mass present in a liter of solution.
Mathematically, density =
As it is given that density of water is 1 g/ml and volume is 175 mL. So, mass of water will be calculated as follows.
density =
1 g/ml =
mass = 175 g
It is known that 18 g of water contains 1 mole of water. Hence, number of moles present in 175 g of water will be calculated as follows.
No. of moles =
=
= 9.72 mol
This means that we have 9.72 moles of ethanol also.
Hence, volume of ethanol present in 175 ml of water will be as follows.
No. of moles of ethanol =
9.72 mol =
Volume = 566.69 ml
Thus, we can conclude that 566.69 ml volume of ethanol contains the same number of molecules as are present in 175 ml of .
It has 36 electrons because it electrons are equal to the amount of protons
