The idea is to convert each hexadecimal digit separately, filling out with zeros to the left so that you have 4 bits for each hex digit. For example, 5 = 0101. Repeat for the other numbers, and write them one after the other. You should learn to do this in your head, or using pencil and paper; but in case of doubt, you can quickly check this with the Windows calculator.
Computers do much of their processing in binary. Hexadecimal is used as a kind of shortcut (easier to read for humans): each hexadecimal digit represents four binary digits.

That can't be an octal number; it has an 8 in it.
0xFFEF + 1 = 0xFFF0.

It is 1010101111001101.
The binary equivalent would be... 1010101101011101 - There is a multi-functional calculator built-in to Windows which can covert numbers between Hex, Decimal, Octal and Binary.
You don't use binary because it's very hard reading a bunch of zeros and ones. You use hexa because each hexa digit corresponds to 4 bits, this makes it very easy to convert from hexa do binary and vice versa. For a similar reason you use octal because each digit corresponds to 3 binary digits. Example: 0101 10102 Has 8 binary digits so it will be 2 hexa digits: 01012 = 516 , 10102 = A16 So the full number will be: 0101 10102 = 5A16 This works for hexa and octal because 16 and 8 are powers of 2, it would also work for 4, 32, 64 or any other ower of 2 . Since 10 for decimal notation is not a power of 2 converting from binary is not so direct.

The number of atoms is indicated by prefixes as mono, di, tri, tetra, penta, hexa, etc.Examples: uranium hexafluoride - UF6, triuranium octaoxide - U3O8.
It is C

SCl6. Since it is a binary molecular compound, for each atom in the molecule you show the correct number of each atom by a prefix, and hexa means 6. There is no point in using any prefix if there is just 1 atom.
Binary molecular compounds are named according to the number of atoms in the compound. Each part gets its own prefix.For example:H2O= Dihydrogen monoxideMgO= Magnesium monoxideBr2O7 = Dibromine heptoxideCaO= Calcium monoxideBr4Cl8 = Tetrabromine octachloride
The hexadecimal system is a base 16 system, just as binary is base 2 and decimal is base 10. The same way that a binary system is more practical for hardware and software implications, hexadecimal is great for easy viewing of binary numbers. It's a lot easier, in the opinion of most, to look at 1FE4 than it is to get the same information as quickly from 0001111111100100. Hexadecimal numbers can also be easily converted to the seven segment display commonly used on electric signs and scoreboards to display numbers and some letters.
