The relationship between the capacitance, the charge on the capacitor and the potential difference applied across its plates is

C= (Q)/(V)
where C is the capacitance, Q is the charge and V is the potential difference.

In our problem,
C=0.30 \mu F and
V=9.0 V, so if we re-arrange the previous formula we can find the charge stored in the capacitor:

Q=CV=(0.30 \mu F)(9.0 V)=2.7 \mu C
