Question

An experiment shows that 113 mL gas sample at pressure of 721mmHg changed to 901 mmHg.

What is the new volume?

Answer 1

90.4 mL

Step-by-step explanation:

Step 1: Given data

• Initial volume of the gas (V₁): 113 mL

• Initial pressure of the gas (P₁): 721 mmHg

• Final volume of the gas (V₂): ?

• Final pressure of the gas (P₂): 901 mmHg

Step 2: Calculate the final volume of the gas

According to Boyle's law, the volume of a gas is inversely proportional to the pressure. We can calculate the final volume of the gas using the following expression.

P₁ × V₁ = P₂ × V₂

V₂ = P₁ × V₁ / P₂

V₂ = 721 mmHg × 113 mL / 901 mmHg

V₂ = 90.4 mL
