The population would decrease, the more predators there are the more food needed for the species .
To determine the mass of the sample, first find the volume difference after and before the aluminum was placed, the volume change is equal to the volume of the submerged object, in this case aluminum.
Then knowing volume of aluminum and the density of it, we can solve for the mass.
D = m/v
Dv = m
2.7 g/ml • 8 ml = 21.6 grams.
46 is the answer. because if you add 26 and 20 that is the mass
The answer is B because isotopes have the same number of protons and neutrons.
