what do you understand by the statement density of gold is 19.6 gm/cm3?
A cm^3 is a block that is a cm x cm x cm.
If you have a piece of gold that is that size. 1 cm x 1cm x 1cm then it will have a mass of 19.6 grams.
Just another note a cubic cm is also equal to a milliliter.
Density og gold is 19.6gcm-³ . Express the density in kgm-³
The statement "density of gold is 19.6 gm/cm3" means that gold has a mass of 19.6 grams per cubic centimeter of volume. Density is a physical property that describes how much mass is packed into a given volume of a substance. In the case of gold, for every 1 cubic centimeter of space it occupies, it has a mass of 19.6 grams.
The statement "density of gold is 19.6 g/cm³" refers to a physical property of gold. Density is a measure of how much mass is contained in a given volume. In this case, it means that for every cubic centimeter (cm³) of gold, there is a mass of 19.6 grams (g).
To understand this statement, you can use the formula for density:
Density = Mass ÷ Volume
In this case, the density value of 19.6 g/cm³ means that if you take a cubic centimeter of gold, it will weigh 19.6 grams. This value is specific to gold and is a constant property regardless of the sample size.
To measure the density of gold, you need to measure its mass and volume. The mass can be determined using a scale, and the volume can be measured by various methods, such as using a graduated cylinder or displacement method.
By dividing the mass of the gold sample by its volume, you can calculate its density. For example, if you have a gold sample weighing 39.2 grams and its volume is 2 cm³, you can calculate its density using the formula:
Density = 39.2 g ÷ 2 cm³ = 19.6 g/cm³
Remember that density is an intensive property, meaning it remains constant regardless of the size or shape of the sample.
