Answer:

0.26 L

Explanation:

Data given

Volume of acetic acid (HC₂H₃O₂)  (V1) = ?

Molarity of acetic acid (HC₂H₃O₂) (M1) = 17.4 mol/L

Volume of acetic acid (HC₂H₃O₂)  (V2) = 4.5 L

Molarity of acetic acid (HC₂H₃O₂) (M2) = 1.0 mol/L

Solution:

As we diluting the concentrated acetic acid (HC₂H₃O₂)

So, Dilution formula will be used

                M1V1 = M2V2

Put values in above equation

           17.4 mol/L x V1 = 1.0 mol/L  x  4.5 L

Rearrange the above equation

             V1 = 1.0 mol/L  x  4.5 L / 17.4 mol/L

             V1 = 4.5 mol / 17.4 mol/L

             V1 = 0.26 L

So 0.26 L of acetic acid (HC₂H₃O₂) is required

Which statement describes how technology has increased our information on Mars?
Luden [163]

The Curiosity rover found sulfur compounds in rocks and carbon in organic compounds like propane, butene, benzene, toluene and thiophene.

It detected methane, not in soil samples, but in the Martian atmosphere.

It did not discover helium in underground pockets. The hole it can drill is only 5 cm deep.

1. Determine the amount concentration of calcium ions and acetate ions in a 0.80 mol/L
PIT_PIT [208]

Since there is one mole of Ca^2+ in calcium acetate, its concentration is 0.80 mol/L.

<h3>What is concentration?</h3>

The term concentration has to do with the amount of substance in solution. The concentration can be measured in several units. Generally, concentration is expressed in molarity, molality, mass concentration units or percentage.

Now we are asked to find the amount concentration of calcium ions and acetate ions in a 0.80 mol/L solution of calcium acetate. The formula of calcium acetate is Ca(CH3COO)2.

Thus;

Ca(CH3COO)2(aq)  ----> Ca^2+(aq) + 2CH3COO^-(aq)

It then follows that since there is one mole of Ca^2+ in calcium acetate, its concentration is 0.80 mol/L.
