ExtremeBDS [4]

Answer:

4560 Torr

Explanation:

<u>Boyle's Law</u>

$\sf P_1 \cdot V_1=P_2 \cdot V_2$

where:

$\sf V_1$ = initial volume
$\sf V_2$ = final volume
$\sf P_1$ = initial pressure
$\sf P_2$ = final pressure

Given:

$\sf V_1$ = 4 L
$\sf V_2$ = 1 L
$\sf P_1$ = 1.5 atm

Substituting the given values into the formula:

$\implies \sf 1.5 \cdot 4=P_2 \cdot 1$

$\implies \sf P_2=6\:atm$

To convert atm to Torr, multiply atm by 760:

$\implies \sf P_2=6\cdot 760=4560\:Torr$
