Answer: The pressure will be 18.05 atm.
Explanation: Expression for ideal gas equation is :
where,
P = Pressure of the gas = ? atm
V = Volume of the gas = 0.333L
n = Number of moles of gas = 0.250 moles
R = Universal gas constant =
T = temperature of the gas = 20°C = (273 + 20)K = 293K
Putting values in above equation, we get:
P = 18.05 atm
The volume of 0. 250 m sulfuric acid solution would be needed to react completely with 18. 00 ml of 0. 350 m ammonia solution is 0.0504 L.
The balance reaction is 2KOH+=
This shows us that we need 2 moles of KOH for each mole of sulfuric acid.
So, we write mathematically 2*(0.018*0.350)=(V*0.250)
V=(2*0.018*0.350)/0.250=0.0504 L
<h3>Sulfuric acid</h3>With the chemical formula H2SO4, sulfuric acid, also known as sulphuric acid or oil of vitriol, is a mineral acid made up of the elements hydrogen, oxygen, and sulfur. It is a viscous liquid that is miscible with water and is colorless, odorless, and viscous.
Since pure sulfuric acid has a significant affinity for water vapor, it does not naturally occur on Earth; as a result, it is hygroscopic and rapidly collects water vapor from the atmosphere. Due to its potent dehydrating and oxidizing qualities, concentrated sulfuric acid is extremely corrosive to various materials, including rocks and metals. One significant exception is phosphorus pentoxide, which dehydrates sulfuric acid to sulfur trioxide instead of being dehydrated by sulfuric acid.

Using formula:
-(1)
where w is weight of object,
m is mass of the object, and
g is the acceleration of gravity.
mass, m = 6 lbm (given)
acceleration of gravity, g = (given)
Now, substituting the values in equation (1):
Since,
So,
Hence, the mass of an object is 5.976 lbf.
