Answer
Please see the work below.
Work Step by Step
Let us assume that each gas obey's gas law
so $Partial \space pressure= Percentage \space composition \times total\space pressure$
We plug in the known values to obtain:
$P_{CO_2}=0.965\times 9\times 10^6Pa=8.7\times10^6Pa=8.7MPa$
$P_{N_2}=0.035\times 9\times 10^6Pa=0.31\times 10^6Pa=310KPa$
$P_{SO_2}=0.0015\times 9\times 10^6Pa=0.0014\times10^6Pa=1.4KPa$
