No one is going to do your homework for you.

To get you started:

You will need a load cell or some form of mass sensor. How you read the value from it depends on the sensor used, if it's analog then that's easy, if it's digital then there may be a library available already.

It is than some basic c / c++ programming to scale the value to give the units you want and output that on a serial port or to a display. How you output it on a display depends on the display you use.

Google "hx711" - Its a load cell to SPI IC and there are plenty of cheap boards that you can buy to interface to an mbed to get started.
