Question

What is the initial pressure of a gas if it’s occupied a volume of 0.375 L but now occupies a volume of 1.25 L at a pressure of 95.5 K PA

Answer 1

318 kPa

Step-by-step explanation:

Step 1: Given data

• Initial pressure (P₁): ?

• Initial volume (V₁): 0.375 L

• Final pressure (P₂): 95.5 kPa

• Final volume (V₂): 1.25 L

Step 2: Calculate the initial pressure of the gas

Assuming constant temperature and ideal behavior, we can calculate the initial pressure of the gas using Boyle's law.

P₁ × V₁ = P₂ × V₂

P₁ = P₂ × V₂ / V₁

P₁ = 95.5 kPa × 1.25 L / 0.375 L = 318 kPa
