Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. Therefore the answer is true.
It would have 8 neutrons. Since the atomic number = the number of protons in the atom, oxygen has 8 protons. If the atomic mass is made up of protons and neutrons, then it would have 8 neutrons as well (8+8=16)
Density is defined as " the ratio of mass of the substance to its volume ". i.e.
d = m/v ------------------------ (1)
volume of the steel sample is required, so putting mass of the steel sample and its density in equation (1),
8 = 80 / v
It implies that,
v = 80 / 8
v = 10 cm^3
