Using the measurements in the table, determine which unidentified metal has the lowest density
volume mass
a 12.5 cm3 122g
b 14.2cm3 132 g
c 18.1 cm3 126g
d 12.7cm3 126g

Explanation:

elements make up everything, and they combine to make compounds.

the answer is c

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.
