Solving the Capacitor Charging Problem

[ShEeRMiLiTaNt]

Hello Everyone,
I need to solve this problem:
How many seconds does it take to charge a 7.7 x 10^-7 farad capacitor to 70V if it is initially uncharged, then connected to a 190V battery through a 11000 ohm resistor.

What I have so far:
q = CV
q = (7.7 x 10^-7f)(70V)
q = 5.39 x 10^-5C

q = q₀e^-t/RC
5.39 x 10^-5 = q₀e^{-t/(11000)(7.7 x 10-7)}

What is q₀ here?

just multiply the capacitance by 190V.
