Question

A 32.4 L gas sample at STP is compressed to a volume of 28.4 L, and the temperature is increased to 352 K. What is the new pressure of the gas in atmospheres

Answer 1

1.47 atm

Step-by-step explanation:

Step 1: Given data

• Initial volume (V₁): 32.4 L

• Initial pressure (P₁): 1 atm (standard pressure)

• Initial temperature (T₁): 273 K (standard temperature)

• Final volume (V₂): 28.4 L

• Final pressure (P₂): ?

• Final temperature (T₂): 352 K

Step 2: Calculate the final pressure of the gas

We can calculate the final pressure of the gas using the combined gas law.

P₁ × V₁ / T₁ = P₂ × V₂ / T₂

P₂ = P₁ × V₁ × T₂ / T₁ × V₂

P₂ = 1 atm × 32.4 L × 352 K / 273 K × 28.4 L = 1.47 atm
