76.2 torr

Boyle's law $P_{1} \times V_{1} = P_{2} \times V_{2}$ $P_1 xx V_1 = P_2 xx V_2$

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

$P_{1} = 242 t$ $P_1 = 242 t$
$V_{1} = 17.0 m l$ $V_1 = 17.0 ml$
$P_{2} = P$ $P_2 = P$ (unknown)
$V_{2} = 54.0 m l$ $V_2 = 54.0 ml$

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

$\frac{242 \times 17.0}{54.0} = P$ $(242 xx 17.0)/ 54.0 = P$

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
