Water = H2O
Number of molecules in one mole of water = 6.022 × 10²³ [Avogadro's constant]
Given number of molecules = 2.52 × 10²³
So,
------
Number of moles =
HOPE IT HELPS
Rutherford's atomic structure model was revolutionary. Contrary to J.J. Thompson's "plum pudding" model (which consisted of a solid, even mixture of protons and electrons), Rutherford's model consisted of one small, positively charged, dense nucleus, a layer of empty space, and a layer of negatively charged electrons. He came to this conclusion through his gold-foil experiment. He shot a ray of alpha particles towards the thin gold foil, and to Rutherford's surprise, some of the rays reflected back instead of going straight through the foil as he originally thought.
Answer:
Explanation:
Hello,
In this case, since the molarity is computed by:
Whereas the solute is the hydrochloric acid, we compute the corresponding moles with its molar mass (36.45 g/mol):
Next, since the solution contains both HCl and water, we compute the volume in liters by using its density:
Therefore, the molarity turns out:

Answer:
When the surface of a mineral reflects light in manner that is similar to a metal, the mineral is said to have a <u>metallic luster.</u>
Explanation:
A mineral is a pure, naturally occurring, solid chemical substance. They have a crystalline structure and a definite chemical composition.
Another physical property that can be used to define a mineral is luster. It can be of two types: metallic luster and non-metallic luster.
A mineral is said to have a metallic luster, if it has high reflectivity like a metal. Examples : pyrite, galena.
