The answer would be wavelength, so b
To find the number of moles from a mass given, simply look to the formula n (moles) = m (mass, g) / MM (molar mass).
Mass was given, 36.04
Molar mass is the total atomic mass of all the atoms present. Water is H20, so that means 2 hydrogen and 1 oxygen. The atomic mass of hydrogen is 1 and atomic mass of oxygen is 16. Therefore MM= 1 + 1 + 16= 18.
Plug that value in and the full equation is
n = 36.04/18
n = 2.002 moles
= 2 moles

The reason why the number I calculated for Avogadro’s number may match the actual number is because the comparison of the number of molecules in the top layer to the number of moles in the top layer is the definition of Avogadro’s number. It is the amount of molecules in a mole <span>of any given substance.</span>
