Which change will create a more dilute solution?

Chemistry
2 answers:
dedylja [7]3 years ago

I think the correct answer would be the third option. The change that will create a more dilute solution should affect the amount of the solvent since it is the component that is greater than the solute. Being dilute would mean there is a very small amount present of a solute in a solution. Increasing the amount of the sovent, would result to a lesser concentration of the solute.

Answer:

increasing the amount of solvent

Explanation:

Solvent is the species which is present in larger amount as compared to solute in a solution

Dilution is reverse of increasing concentration

When we use term concentration we consider the amount of solute present in a solution.

1) When we add more solute to a solution, we increase the concentration of the solution with respect to solute.

2) When we decrease the amount of solvent in the solution we are increasing the concentration of the solute (the amount of solute per unit amount of solvent increases). So by evaporating the solvent we are decreasing the amount of solvent and thus increasing the concentration of solution.

3) when we increase the amount of solvent we are decreasing the concentration of solute per unit of solvent. It means we are diluting the solution.

4) increasing the volume of the solution means no change in concentration. As it means we are adding more of solution of the same concentration to the solution of previous concentration.

The mole is defined as the amount of a substance containing the same number of particles as exactly 12 g of C-12. The amu is def
Pavlova-9 [17]

Answer:

Because it wouldn't make any sense

Explanation:

First of all, I think it's important to highlight the definition of isotope.

Isotope (Wikipedia): Variants of a particular chemical element <u>which differ in neutron number</u>...

This means that two isotopes are the same element but have different net mass per atom, due to the different number of neutrons.

Therefore, it's important to make the definition on the same isotope so that the proportion is equal. If the definition would be made on different isotopes, the proportion wouldn't have any sense. Let me be clear with this example:

mass in grams of a C-12 atom = 1.9944235 × 10 ^ -23 g  --> this is the mass of a single C atom.

By definition --> 1 mol of anything = 6.02 x 10 ^ 23 particles of anything

Therefore, we know how much a single C atom weights. How many grams do you think that 6.02 x 10 ^ 23 atoms of C (i.e a mol of C) could weight??

1 single C atom ----------------------------- 1.9944235 × 10 ^ -23 g

6.02 x 10 ^ 23 atoms of C   ------------ <u>12.006 g  !!</u>

These 12 g is the same quantity than above! Therefore, 1 mol of C weights 12 g. If the definition were made with 13 g of C-13 (the other C isotope), these numbers will not be the same --> There would be a contradiction.

Regarding the second question, we need to search Ne-20 atomic mass in grams -->  3,3509177 × 10 ^ -23 g

Hence, if we follow the same rule, the amu would be 1/12 of Ne-20.

[ 3,3509177 × 10 ^ -23 g ] / 12 = 2.79 ^ -24 g
