1) The IC 4049 is a CMOS logic chip.
2) It includes the six independent inverters inside.
3) We often use them for interfacing.
And, make simple clock pulse generators and oscillators.
4) When connecting two in series to make a non-inverting buffer.

IC 4049 is a square wave oscillator. It has six independent inverters; each of it has an input and an output. so 6 x 2=12.
Totally, 12 pins are for i/p and o/p. pins 13 & 16 have No Connections. pins 1 & 8 are for power supply and ground.

But it doesn't mater whether its hex inverter or not because, even 7404 IC is a hex inverter but has 14 pins.
HEX just indicates that the ic chip contains 6 inverters, that's it. It has no relation with the pins.

Inverter : 1 input 1 output
Hex inverter: 6 input 6 output
That constitutes 12 pins
2 not connected
2 Vcc and Gnd
Thus, total = 12+2+2=16

2 not connected.
1 VCC and 1 VDD.

Can anyone tell an easy way to identify the number of pins with the help of its IC number?

Why should we used 2 Vcc and Gnd. Every IC should have 1 Vcc and gnd. It may have 14 pins?

How do you say it is a hex decimal. Any can explain me, please?

How did you say that 4049IC is a hexa decimal inverter?
