Ihave 2 m3 of mineral ore sample. it has a mass of 1 x 194 kg. calculate the density of the ore sample and express your results in g/cm3 with the appropriate scisntic notion.

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

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
