You can use displacement of water but you'll have to do it quickly before the sugar dissolves. You can also find a substance that sugar does not dissolve in and use that instead of water. If you change its state of matter, the volume might change.
By displacement of liquid
Concentration increases
The volume increase.
.01kg
Because the Sugar molecules are dissociated and fit in the space of H2O molecule arrangements. Hence no increase in the volume.
Molarity is moles in every litre. Therefore you have to convert this to find out the moles in each litre. 21/52 is 0.404 molar.
The problem you would have is that the sugar cube would not be at its regular size so to solve that you would have to put the water in first and then put the sugar cube in it. After that is done then record the volume the sugar starrts to melt into the water.
Concentration increases
that's just like asking how many grains of sand are on a beach...... what you could do is... measure the size of a grain of sugar - width, length, height and times these together to find its volume. then empty a bag of sugar and fill it with water, until where the sugar reaches when filled. pour the water into a measuring jug - you now have the volume of sugar that the bag takes in cm3. the grains of sugar will have a few air spaces between them so take a rough guess at this amount - maybe 1-2cm3 now minus this from the volume of the bag. divide the volume of the bag by the volume of one grain of sugar. this will be an approximate figure of how many grains there are.
The volume of a sugar and water mixture is less than the volume of each substance alone because when water is added to sugar, water fills in the little spaces between the particles of sugar, resulting in a lower volume.
The volume increase.
Yes there is a change in volume.
Let's imagine the following objects first: Sugar cubes are solid blocks, each with a comparatively larger volume. Granulated sugar is fine and particulate, and each grain has a very small volume. It is only logical that when comparing one block of sugar to one grain of sugar, that the grain dissolves faster because it has a smaller volume (less to dissolve), and the surface area to volume ratio is much higher.

Because the Sugar molecules are dissociated and fit in the space of H2O molecule arrangements. Hence no increase in the volume.
a sugar cube has air spaces in it. when put in water, the spaces will fill. the volume of water displaced will therefore be less than the original volume of the cube, so no
