A $7\mathrm{.}7-F$ capacitor is charged by a $160-V$ battery $($see a$)$ and then is disconnected from the battery. When this capacitor $(C_1)$ is then connected $($see

b$)$ to a second $($initially

uncharged$)$ capacitor, $C_2,$ the final voltage on each capacitor is $17V.$

Part A

What is the value of $C_2?[$Hint: charge is conserved.$]$

Express your answer using two significant figures and include the appropriate units.

$C_2=$
