At what pressure will 1.88 L of gas at 3.81 atm pressure change to a volume of 2.22 L?
Assume constant n and T; P1V1 = P2V2

3.23 atm

Explanation:

Use the equation P₁V₁=P₂V₂.  P₁ and V₁ are initial pressure and volume.  P₂ and V₂ are final pressure and volume.  Solve for P₂.

(1.88 L)(3.81 atm) = (2.22 L)(P₂)

7.1628 L*atm = (2.22 L)(P₂)

P₂ = 3.226 atm

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
