Mass number is the number of protons and neutrons in an atom, and it tells us about the mass of the atom in amu, or atomic mass units. Atomic mass is the average mass of all the isotopes of a certain type. It is a weighted average that takes into account the abundances of all of the different isotopes

Answer:
<h3>The answer is 235.29 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question.
density = 0.017 g/mL
mass = 4 g
We have
We have the final answer as
<h3>235.29 mL</h3>
Hope this helps you
Anything with a pH level of 3, 2, or 1.
Explanation:
Water is a polar solvent as the hydrogen and oxygen atom has large difference in their electronegativities.
Oxygen atom is highly electronegative as compared to hydrogen atom therefore, it pulls the electrons of hydrogen atom closer towards itself.
As a result, two poles will create forming a partial positive charge on the hydrogen atom and partial negative charge on the oxygen atom.
Thus, we can conclude that high electronegativity difference between oxygen and hydrogen is the cause of polarity in water molecules.
