Answer:
P₂ = 1.92 atm
Explanation:
According to the boyle's law:
The pressure of given amount of gas at constant temperature and number of moles of gas is inversely proportional to the volume.
P₁V₁= P₂V₂
Given data:
Initial volume = 4.00 L
Initial pressure = 1.20 atm
Final volume = 2500 mL
Final pressure = ?
Solution:
First of all we will convert the volume into litter.
2500 mL × 1L/1000 mL = 2.5 L
P₁V₁ = P₂V₂
P₂ = P₁V₁ /V₂
1.20 atm×4.00 L = P₂ ×2.5 L
P₂ = 1.20 atm×4.00 L/ 2.5 L
P₂ = 4.8 atm. L/ 2.5 L
P₂ = 1.92 atm
