<span>2.188*10^23 atoms of iron
6.022*10^23 atoms/mole
(2.188*10^23 atoms of iron)/(6.022*10^23 atoms/mol)~.3633 moles of iron
Hope this helps!</span>
Answer:
Gas
Explanation:
Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.

I would say a. lithium but i am not sure.
Molarity is equal to the number of moles of solute per liter solution.
number of moles solute: (molar mass of perchloric acid is 100.45 g/mol)
35.0 mL * (<span>1.67 g/mL) *0.705 * (mol/100.45 g) = 0.41 moles
liter solution = 2000 ml * (1 L/1000 ml) = 2 L
molarity is equal to 0.41 moles/ 2 L =0.205 M</span>
