The initial water volume in this container was 10.0 mL. When the key was submerged, 3 volumes of displaced water were collected: 0.7 mL, 0.8 mL, and 0.9 mL. What is the volume of the key? mL

in theory, limestone is composed principally of the compound calcium carbonate - caco3, but in reality this compound is deposited in conditions involving a number of other compounds as impurities so it ends up being a mixture of many compounds.

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.
