Density can be calculated using the following rule:
density=mass/volume
therefore,
volume=mass/density
we have mass=0.451g and density=0.824g/ml
substituting in the above equation, we can calculate the volume as follows:
volume = 0.451/0.824 = 0.547 ml
Answer:
A. 32.06 g/mol
Explanation:
The molar mass units are always g/mol
A magnet creates an invisible area of magnetism all around it called a magnetic field. The north pole of a magnet points roughly toward Earth's north pole and vice-versa. That's because Earth itself contains magnetic materials and behaves like a gigantic magnet
Answer:
nerve cell, nervous tissue, brain, nervous system, human.
Explanation:
The order is from the simplest to the most complex, within the simplest would be the cellular structure, then the organs come, then systems (a set of organs in multidirectional operation among them) and finally the human, which is a set of systems .
Explanation:
Just a few things to remember:
-
# of neutrons = Mass number - # protons
-
Mass number = # protons + # neutrons
-
Atomic Number = # of protons
- # of electrons = # of protons - charge on the atom
-
Symbol - use the atomic number to find the element in the periodic table
