The subnet mask /24 means that the first 24 bits of the IPv4 address are used for the network portion, leaving 8 bits for the host portion. With 8 bits for the host portion, there are 2^8 or 256 possible combinations, but one of these combinations is used for the network address (162.48.128.0) and another is used for the broadcast address (162.48.128.255). Therefore, there are 256 - 2 = 254 possible addresses for the hosts.
