What is the Molarity of a solution that contains 0.887 moles of NaOH in 310ml of water?
20 POINTS! HELP!

Hey there! :

number of moles = 0.887 moles of NaOH

310 mL in liters = 310 / 1000 => 0.31 L

Therefore:

M = moles of solute / volume in liters solution

Molarity = 0.887 / 0.31

Molarity = 2.86 M

Hope this helps!

the answer is d. 74.02

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
