76.2 torr

#### Explanation:

Boyle's law ${P}_{1} \times {V}_{1} = {P}_{2} \times {V}_{2}$

Pressure and Volume are inversely related. As the Volume increases the Pressure Decreases

${P}_{1} = 242 t$
${V}_{1} = 17.0 m l$
${P}_{2} = P$ (unknown)
${V}_{2} = 54.0 m l$

$242 \times 17.0 = P \times 54.0$ Divide both sides by 54.0

$\frac{242 \times 17.0}{54.0} = P$

76.185185 = P (Since there are only three significant digits in the problem there can be only three significant digits in the answer.)

76.2 torr = P
