Question

The pressure of a gas is 750.0 torr when its volume is 400.0mL. Calculate the pressure (in atm) if the gas was allowed to expand to 600.0mL at constant temperature. (UNITS!!)

Question 4 options:

0.660 atm


1.48 atm


500.0 atm


1125 atm

Answer 1

please make me as braniest

Answer 2

Given :

$P_{1}$ = 750 torr

$V_{1}$ = 400 mL

$V_{2}$ = 600 mL

To Find :

The pressure (in atm) if the gas was allowed to expand to 600.0mL at constant temperature.

Solution :

We know,

At constant temperature, $P_{1} V_{1}$ = $P_{2} V_{2}$ (By Boyle's Law)

or,                           750 × 400  =  $P_{2}$ × 600

or,                                          $P_{2}$ = $\frac{750 X 400}{600}$

∴                                            $P_{2}$ = 500 torr = 0.66 atm

Option (1) is correct.
