The amount, in grams, of ethanol needed to prepare 268 grams of a 9.76 M solution of ethanol in water will be 120.50 grams
<h3>Solution preparation</h3>
In order to prepare 268 grams of solution, 268 mL of water would be needed because 1 mL of water weighs 1 gram.
Since we now know the volume of solution that we want to prepare, the amount of solute (ethanol) that would be required in order to make a solution of 9.76 M will be:
Mole required = 9.76 x 268/1000 = 2.62 moles
Mass of 2.62 moles ethanol = 2.62 x 46.07 = 120.50 grams

<span>subshells have two reasons of stability-
</span><span> 1) half filled and full filled subshells lead to symmetry as symmetry always increases stability in the nature.
</span>2)<span> in half filled and full filled subshells there are maximum no Of exchanges so exchanges releases energy so it increase stability.. Exchange of e-s also can b understood as delocalization of e-s which is similar like resonance and resonance always increases stability</span>
Answer:
True
Explanation:
Earth is a single interconnected system but it can be subdivided into smaller systems.
Answer: Metallic Bonding.In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
Explanation:
