Firstly, why do you think you are dividing by 2?
As for the multiplication by 5, I don't see how that fits in.

The mark scheme says that you need to multiply by 5 which is what I don't understand. I thought that you divide the values by 2 as that's the volume but I may be wrong :|

You're right. To get concentration you divide moles by volume.
But what's the units of volume?
Spoiler
The volume they give you is 200cm3 How do you convert that to the new units?
I really don't see why the multiplying by 5 is necessary..
