Relative density, also known as specific gravity, is a ratio of the density of a substance to the density of a reference substance (usually water for liquids and solids). Since this ratio compares densities, it is typically expressed as a dimensionless number and cannot exceed 100 percent (or a value of 1) for a substance with respect to water. However, if the reference substance is different or if the context implies a comparison with a different material, the relative density could have values greater than 1, but it still represents a comparative measure rather than an absolute percentage.

What the formula for relative density?
The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water. Thus for solids or liquids: Relative density = denisty of substance (kg/m3) / density of water (kg/m3) Relative density therefore has no units, it is a number, and indicates only how many times more dense the substance is than water. The relative density of water is 1 or 1000 kg/m3.
Which has more alcohol in it a solution of one percent by volume or one percent by weight?
One percent by weight. Alcohol has a density of less than water, so 1 g of alcohol is more than 1 mL.
Is 0.15 percent more than .075 percent?
Is 0.15 percent more than .075 percent?
Which is more 3.33 percent or 50 percent?
50% is more than 3.33%.
Can percent error be more than 5 percent?
Yes. In some cases it can be much more than five percent.
How is the relative density of an object determined?
The relative density of an object is determined by comparing its density to the density of water. It is calculated by dividing the density of the object by the density of water. If the relative density is less than 1, the object will float in water; if it is greater than 1, it will sink.
What is the relative density in water?
The relative density in water refers to how dense a substance is compared to water. If the relative density is greater than 1, the substance will sink in water. If the relative density is less than 1, the substance will float in water.
What the formula for relative density?
The relative density of a substance is the ratio of its density to the density of some standard substance. The standard substance for solids and liquids is water.

They say that blood is thicker than water The relative density of water is 1.00 What is the relative density of blood?
1.06
What does relative density mean?
Relative density, also known as specific gravity, is a measure of the density of a substance compared to the density of a reference substance (usually water). It is a dimensionless quantity and is used to describe the heaviness of a substance in relation to water. A relative density greater than 1 indicates that the substance is denser than water, while a relative density less than 1 indicates that it is less dense.
What is meant by relative density of a substance?
Relative density, also known as specific gravity, is a measure of how much denser a substance is compared to another substance, usually water. It is calculated by dividing the density of the substance by the density of water. A relative density greater than 1 means the substance is denser than water, while a relative density less than 1 means the substance is less dense than water.
Is an oil with the density 0.9 denser than water?
No, relative density is relative to water. Therefore, oil with a relative density of 0.9 is 90% the density of water. Which is why oil floats on top of water. Put both in a glass to see.
What is the relative density plastic cube?
The relative density of a plastic cube is the ratio of the density of the plastic cube to the density of water. To calculate it, you would divide the density of the plastic cube by the density of water (usually 1 g/cm^3). If the relative density is less than 1, the cube will float in water, and if it's greater than 1, the cube will sink.
What is relative density aluminium?
Relative density, also known as specific gravity, is the ratio of the density of a substance to the density of a reference substance. For aluminum, its relative density is approximately 2.7, meaning it is 2.7 times denser than water.
Which has more alcohol in it a solution of one percent by volume or one percent by weight?
One percent by weight. Alcohol has a density of less than water, so 1 g of alcohol is more than 1 mL.
What is relative densities?
Relative density is the ratio of the density of a substance to the density of a given reference material.If a substance's relative density is less than one then it is less dense than the reference; if greater than 1 then it is denser than the reference. If the relative density is exactly 1 then the densities are equal
What if the relative density of paper?
The relative density of paper is typically around 0.5 to 1.5, depending on the type of paper and its composition. This means that paper is generally less dense than water, since water has a relative density of 1.
