The molarity of the solution can be used to give the moles and the volume of the solution. The 0.0140 M sodium thiosulfate needs 225 ml of volume.
<h3>What is molarity?</h3>
Molarity is the property of the solution that is given by the ratio of the moles of the solute to the volume of the solution in liters.
Given,
Molarity of Sodium thiosulfate = 0.0140 M
Mass of solute (AgBr) = 0.590 gm
Molar mass of AgBr = 187.77 g/mol
First moles from the mass can be calculated as,
Moles = mass ÷ molar mass
n = 0.590 g ÷ 187.77 g/mol
= 0.00314 moles
Now, the volume of the solution from molarity is calculated as,
Volume = moles ÷ molarity
= 0.00314 moles ÷ 0.0140
= 0.225 L
Therefore, 225 mL is the volume required.

Answer:
solids
Explanation:
through solids because the molecules are closer together
Explanation:
Whether you choose to use van der Waals radii or metallic radii as a measure of the atomic radius, for metals the ionic radius is smaller than either, so the problem doesn't exist to the same extent. It is true that the ionic radius of a metal is less than its atomic radius (however vague you are about defining this).
Answer:
All objects can have the same size but have a different mass!
This is true, although it sounds fake. This is one example, there is a Neutron star, and Neutron stars are as big as a city, but they have a mass which is hundreds of times greater than our sun's mass. Because of them having so much mass, they are also having so much gravitational energy, which makes them also have gravity. They're so small, but have so much mass that they can do much. Even a drop of a neutron star can punch open the earth! It's true, so yes, it is possible for objects the SAME size to be having different masses according to that example.
But let's look on how they can have different mass.
They can have different masses becase of different densities. Put a iron ball inside water, and put an apple as close to the iron ball's side, what happens? The apple floats, becuase the apple's mass is less than the water, and the iron ball's mass is MORE than the water. So, because the iron ball is denser than the apple, that's why, it has more mass than the apple. The apple isn't much dense, it isn't as dense as water or the iron ball. But the iron ball is much more denser than the water. So because of the different material densities of the material, that's why it can have different masses.
Remember to Remember those 2 examples I gave you... (neutron star vs sun, iron ball vs apple on water)
