Question #87395

1 Answer

Apr 20, 2017

$3.89 a t m$ $3.89 atm$

Explanation:

Use the formula:
$P_{1} V_{1} = P_{2} V_{2}$ $P_1V_1 = P_2V_2$

$8.12 a t m \cdot 2.19 L = P_{2} \cdot 4.57 L$ $8.12atm*2.19L = P_2 * 4.57L$

$P_{2} = \frac{8.12 a t m \cdot 2.19 L}{4.57 L}$ $P_2 = (8.12atm * 2.19L)/(4.57L)$

$P_{2} = 3.8912035 a t m$ $P_2 = 3.8912035atm$

Since you only have 3 significant figures, the answer is:

$P_{2} = 3.89 a t m$ $P_2 = 3.89 atm$
