# Help, A level chem question

#1
A solution of potassium hydroxide contains 5.60gdm^-3. This solution is used to neutralise 20.0 cm^3 of a solution of sulphuric acid of concentration 0.05moldm^-3.
A)Write an equation for the reaction.
B)Determine the volume of potassium hydroxide solution that is required to neutralise the sulphuric acid.

Hopefully you have worked out the balanced equation?

Step by step we have:

What is the concentration of the potassium hydroxide in mol dm-3 ?
How many moles of sulphuric acid are present in the 20cm3 ?
How many moles of KOH are need to exactly neutralise the acid?
What volume contains exactly that number of moles?
