What is moles?</h3>
Mole, also spelled mol, in chemistry, a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
The mole designates an extremely large number of units, 6.02214076 ×
. The General Conference on Weights and Measures defined the mole as this number for the International System of Units (SI) effective from May 20, 2019. The mole was previously defined as the number of atoms determined experimentally to be found in 12 grams of carbon-12.
The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s constant, in honour of the Italian physicist Amedeo Avogadro (1776–1856). Avogadro proposed that equal volumes of gases under the same conditions contain the same number of molecules, a hypothesis that proved useful in determining atomic and molecular weights and which led to the concept of the mole.

Answer:
The position of the double bond
Explanation:
Answer:
25 atm or 190mmHg
Explanation:
Since Temperature is constant we dont need to worry about it so.
P1V1=P2V2
Rewritten as (P1xV1)/V2 Always use liters in gas laws
I Prefer atm so ill convert to that to use in the equation.
(.5atmx.4L)/.8L =.25 atm or 190mmHg
(You can convert mmHg to atm by dividing by 760)
