density of helium! 10 points!?

a 5cm3 block of lead weights 0.55newtons. The lead is carefully submerged in a tank of mercury. 1cm3 of mercury weights 0.13newtons.

What is the weight of the mercury displaced by the block of lead? will the block of lead sink or float in the mercury?

Can you include the procedure, thank you

    Sorry, but most teachers would consider this cheating :-P

    weight density = W/V

    0.55/5= .11 N/cc

    which is less than mercury, 0.13 N/cc

    therefore

    it floats.
