If you need 52 grams of potassium to make the glass for an arcadia door, how many atoms of potassium would this be?

8.03x10^23 atoms

Explanation:

From Avogadro's hypothesis, we understood that 1mole of any substance contains 6.02x10^23 atoms.

This means that 1mole of potassium will also contain 6.02x10^23 atoms

1 mole of potassium = 39g

Now we can the above question as follows.

If 1 mole(i.e 39g) of potassium contains 6.02x10^23 atoms, then 52g of potassium will contain

= (52 x 6.02x10^23) /39 = 8.03x10^23 atoms

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
