Apiece of metal with a mass of 125 g is placed into a graduated cylinder that contains 25.00 ml of water, raising the water level to 56.00 ml. what is the density of the metal?

density=mass/volume

           =56-25

          =31

D=125/31

density=4.03

b because if you divide 125g with 31g/cm3 you get 4.03g/cm3

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

personal, she chose to do it.
