How to construct memory map and circuit?

have some questions that I am not sure on how to do, please help.

Question:

The capacity of a RAM module is 16K x 8. (i) How many address and data lines does this module have? (ii) How many of these RAM modules are needed to realise a memory module with a capacity of 64K x 16? Explain your answer. (iii) IF the 64K x 16 memory module in (i) starts at 0000H, design a decoder to construct the memory module from the 16K x 8 modules.

I am not sure on how to do find the number of RAM modules for (ii) and therefore, not able to construct the memory map for (iii).

My answer for (i) is 14address lines and 8 data bits.

Thanks for your help.
