I have no idea how to work these type of questions out

Describe how you would use a 1.0 mol dm–3 solution of sucrose to produce 30 cm3 of a 0.15 mol dm–3 solution of sucrose
So you need to work out the number of moles of sucrose in the desired solution. Then using that you can work out the volume of the 1.0 mol dm-3 you would need. Finally, you need to work out how much water you need to add to make the solution up to 30 cm3 (30 - [volume of 1.0 mol dm-3])

Hope this helps
