A container of gas occupies 3.5 L at 585 mmHg. What would the new pressure be if the volume decreases to 2.0L?

1023.75mmHg

Explanation:

V1 = 3.5L

P1 = 585mmHg

V2 = 2.0L

P2 = ?

To solve this question, we'll require the use of Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature is kept constant.

Mathematically,

V = kP, k = PV

P1 × V1 = P2 × V2 = P3 × V3 = = Pn × Vn

P1 × V1 = P2 × V2

Solve for P2,

P2 = (P1 × V1) / V2

P2 = (585 × 3.5) / 2.0

P2 = 2047.5 / 2.0

P2 = 1023.75mmHg

The final pressure of the gas is 1023.75mmHg

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
