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.
