Answer to Question #334215 in General Chemistry for niya

Question

A gas with a volume of 525 rnL at a temperature of �25°C is heated to 175°C. What is the new volume of the gas if pressure and number of moles are held constant

Answer 1

The new volume, in milliliters, of the gas is 948 L

From the question,

We are to determine the new volume of the gas.

From Charles' law which states that the volume of a fixed mass of gas is directly proportional to the temperature (in Kelvin) provided that the pressure remains constant.

That is,

V ∝ T

Then,

V = kT

Therefore, we can write that

Where  is the initial volume

 is the initial temperature

 is the final volume

and  is the final temperature

From the given information,

Putting the values into the formula, we get

V₂ ≅ 948 L

Hence, the new volume, in milliliters, of the gas is 948 L
