How many subnets can be gained by subnetting 172.13.32.0/23 in to /27 mask and how many usable host adresses will be there per subnet?

we have the IP address...0 / his mask is /  (...0)

using the new mask / (...) so we add4 bits to the mask / (- =4 bits)

the number of subnet can be gained   is2 ^4 = subnet

remain5 bits for the host part

Therefore the number of machine by subnet is

2 ^5-2 =-2 = hosts
