drop - down menu to choose the correct unit.
what is the volume of a sample of argon gas, ar, at 744 torr and 55°c if it occupies 13.3 l at 55°c

Explanation:

Step1: Identify the formula

Boyle's Law: \(P_1V_1 = P_2V_2\)

Step2: Assign the values

\(P_1 = 585\ mmHg\), \(V_1 = 755\ mL\), \(V_2 = 482\ mL\), \(P_2\) is unknown.

Step3: Rearrange the formula to solve for \(P_2\)

\(P_2=\frac{P_1V_1}{V_2}\)

Step4: Substitute the values

\(P_2=\frac{585\times755}{482}\)
\(P_2=\frac{441675}{482}\)
\(P_2 = 916.338\ mmHg\approx916\ mmHg\)

Answer:

\(P_1 = 585\), unit: \(mmHg\)
\(V_1 = 755\), unit: \(mL\)
\(P_2=\)?, unit: \(mmHg\)
\(V_2 = 482\), unit: \(mL\)
Calculated value of \(P_2\): \(916\), unit: \(mmHg\)
