Number of pages $= 2k = 2*2^{10} = 2^{11}$

Number of frames $= 512 = 2^9$

Number of bits to represent physical address $= 22$

Page table size = Number of pages * Page table entry size

If no additional information is given then,

Page table entry size = Number of bits to represent frames.

Number of bits to represent frames $=9$

Page table size $= 2^{11} * 9$ bits $= \cfrac{2^{11} * 9}{8}$ bytes
