<span>Now, since the compound NaCl is made of sodium and chlorine, the molar mass of NaCl can be calculated only after its atomic weight is known from the table. Individual atoms of sodium and chlorine have an atomic mass of 22.98976 g/mol and 35.453 g/mol respectively.

Erosion can be created from all of them (All of the above)
Answer:
Silver
Explanation:
I remember this because Ag can mean "Ain't Gold"
#4 and #5:
To find pH given concentration of H+ or H30+
pH = - log (H+ or H30+ M)
To find pH given concentration of OH-
Since you already found the pH for this (in #4), you subtract #4's answer from 14.
14 - (pH) = pOH
Molarity's formula is known as: Molarity(M)=moles of solute/liters solution.
In this case we are already given moles and liters so you just have to plug the numbers into the equation.
0.400 mol HCL/9.79L solution=0.040858M
If you were to use scientific notation, the answer will be: 4.1*10^-2, but otherwise, you can just use the decimals above and round appropriately as you see fit.
