Use a solvent which do not dissolve the solute. For example, if you want to determine the density of sugar, and sugar, as we all know, is soluble in water. So, instead of water we can substitute it with oil.
its volume can only be messured by displacement. it is difficult to equaly devide. it can be difficult to determine density if you are trying to determine the density of the material, not the object.
you can be determine irregular solid by its shapes and if it is not measurable by the ruler .
To determine the density of irregular solids like pebbles, you can use the water displacement method. First, measure the volume of water in a container. Then, add the irregular solid to the water and measure the new volume. The difference in the two volume readings can be used to calculate the volume of the irregular solid. Finally, divide the mass of the pebbles by the volume to calculate the density.
Many solids are soluble in water; other are not soluble.
measure the volume of liquid that the object displaces
To find the density of a rectangular solid object, you would calculate the mass of the object by multiplying its volume by its density. For an irregular solid object, you would typically measure its mass using a balance and its volume using displacement of water, then divide the mass by the volume to find the density. The main difference lies in how you determine the volume of the object, with rectangular solids having a straightforward formula for volume calculation compared to irregular shapes which require more complex methods.
Example of a soluble substance would be sugar and salt, both are easily soluble in the universal solvent, water
Insoluble particles. Some solids are soluble in water and able to be dissolved Some solids are insoluble If a solid is a mixture of both, then some (the soluble part) will dissolve in water; some (the insoluble part) will not and depending on size of the particle will be left in suspension (very small or low density) or sitting at the bottom of the container (large or high density)
Regular solids have all sides the same, irregular solids have different sides.
The substance is usually soluble in water or other solvents such as alcohol. It is called soluble salts
Since mass is usually expressed in grams and volume in cubic centimeters, density is expressed in grams/cubic centimeter. For solids that have an irregular shape, the displacement method must be used to determine their volume. Choose a graduated cylinder large enough to hold the object.
Both are solids !!
