In a 16 bit number there must be from zero to 16 '1'. If a bit does not have value zero then it has a value of 1. Nothing else can be represented by a bit.
Example 0000 is a 4 bit number. Each bit is a zero. 1010 is also a four bit number.
0000111100001111 is a 16 bit number.
1100110011000001 is also a 16 bit number.
16 (decimal) = 10000 (binary).
16 Mb in binary notation can be refered to as 16*1024 bits. A bit is represented with a lower case "b".
A 16-bit binary number
40000(10) = 9C40(16) = 1001110001000000(2)
56 = 32 + 16 + 8 so binary 0011 1000
hexadecimal can express 16 bit binary in 4 place form, not 16.
The most common binary word length for audio is 16-bit. Bit depths of 20- and 24-bit resolution are also commonly used.
216-1 or (2^16)-1
24, or 16 (0 through 15) One binary digit (bit) can have 21 values (0 or 1). Two bits can have 22 values. Three bits can have 23 values. A five-bit number can have 25 values... and so on...

It is 10110100. 128 + 32 + 16 + 4 = 180
