New homes has developed as a result of population growth around Cape Canaveral due to the space program.

<h3>What is population growth?</h3>
  • The rise in the number of people on Earth is referred to as population growth.
  • The majority of human history saw a relatively steady population size.
  • Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialization.
  • Due to broad advancements in public health, nutrition, personal cleanliness, and medicine, the average human lifespan has gradually increased since 1950, which has led to an unparalleled surge in the world's population.
  • The population is one of the crucial elements that balances the ecosystem.
  • It should be in harmony with available resources and methods.
  • A balanced population will make it easier to meet all of the needs and demands of the populace, helping to protect the nation's environment.

What is the volume of 0.25 mol of ammonia gas at 1.00 atm and 273 K? (R= 0.0821 Latm/molK)What is the volume of 0.25 mol of ammo
ICE Princess25 [194]

Answer:

5.6L

Explanation:

Given parameters:

number of moles  = 0.25mol

pressure on gas  = 1atm

temperature  = 273K

Gas constant R = 0.0821Latm/molK

Unknown:

Volume of gas  = ?

Solution:

Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

It is mathematically expressed as;

             PV = nRT

where P is the pressure

           V is the volume

          R is the gas constant

          T is the temperature

          n is the number of moles

All the parameters are in the appropriate units and we simply solve for the volume of the gas;

                1 x V = 0.25 x 0.0821 x 273

                      V  = 5.6L
