Answer: mass and volume
Explanation:
Divide the mass by the volume in order to get an object's Density.
Just put "One can't describe the motion of particles, due to quantum mechanics particles don't take form until they're measured and even once they are there is no way of knowing if that is their actual form".
The good thing about studying Astrophysics is that there is always a way to correctly make a question unanswerable.
Stoichiometry is the field of chemistry that is concerned with the relative quantities of reactants and products in chemical reactions. For example, when oxygen and hydrogen react to produce water, one mole of oxygen reacts with two moles of hydrogen to produce two moles of water
A scientist would measure the amount of carbon-14 (¹⁴C) in a fossil to determine its age.
The ¹⁴C:¹²C ratio is constant in living organisms. When they die, the radioactive ¹⁴C decays, so the ratio changes. The half-life for the for the decay is 5730 a, so scientists can work backwards and calculate how long ago the plant died. The method is good for determining the age of fossils up to 50 000 a old.
