Explain an unknown alkali metal hydroxide is dissolved

Reference no: EM13565721

The problem states that 4.36g of an unknown alkali metal hydroxide is dissolved into 100.0 ml of water. It is then titrated with 2.50 M HCl using an acid-base indicator. The equivalence point is 17.0 ml of HCl.

It then asks (a) what is the molar mass of the unknown alkali metal hydroxide? (b) what is the identity of the alkali metal?

How do you go about solving this problem? I don't even know where to start.
