Question

A sample of helium gas has a volume of 250.0 mL when it pressure is 0.935 atm. If the

Answer 1

Answer:

The answer is

1.336 atm

Explanation:

In order to find the volume of the gas at 175 mL we use the Boyle's law formula

That's

$P _1 V _1 = P _2 V _2$

where

P1 is the initial pressure

V1 is the initial volume

V2 is the final volume

P2 is the final pressure.

Since we are finding the final pressure

$P _2 = \frac{P _1 V _1}{ V _2}$

From the question

P1 = 0.935 atm

V1 = 250.0 mL

V2 = 175 mL

Substitute the values into the above formula and solve

That's

$P _2 = \frac{0.935 \times 250}{175} \\ = \frac{233.75}{175} \\ = 1.33571$

We have the final answer as

1.336 atm

Hope this helps you
