Vinegar is a solution of acetic acid. What is the molarity of the solution produced when 125g of acetic acid (C2H4O2) is dissolved in sufficient water to prepare 1.50L of solution?

Answers

Answer 1

Answer:

Answer: The molarity of solution is 1.39 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=(n)/(V_s)$

where,

n = moles of solute = $\frac{\text {given mass}}{\text {molar mass}}=(125g)/(60g/mol)=2.08mol$

$V_s$ = volume of solution in L

Now put all the given values in the formula of molality, we get

$Molarity=(2.08mol)/(1.50L)=1.39mol/L$

Therefore, the molarity of solution is 1.39 M

Help ASAP please! I don’t understand this at all.

Answers

well i think what you do first is that you would divide that number of amu by 6.02 x 10^23 and that will get you the number of moles of H2. once you have the number of moles you divide the number of moles by the molar mass of H2 and that should give you the grams. i’m trying to explain this as best as possible sorry if ur still confused.

Which type of crystal is typified by a sea of delocalized electronssurrounding the lattice?
O A. lonic
B. Metallic
OC. Macromolecular
D. Chemical
Reset Selection

Answers

The correct answer is option B. Metallic.

What explains the structure of metals and delocalized electrons?

Metal is composed of a huge structure of atoms arranged in a regular pattern. Electrons from the outer shell of a metal atom are delocalized and can move freely throughout the structure. This sharing of delocalized electrons results in strong metal bonds.

Metallic bonds are electrostatic attraction between metal cations and the negatively charged ocean of delocalized electrons. The sea of delocalized electrons contains only valence electrons, not core electrons.
