Heliums density is said to be 0.1786 g/L. Scientists can determine this by getting a liters worth of helium and having that as the volume. Then you find the mass and take away how ever much the mass is that is holding the helium in place. When you get that number you just divide them and then you get 0.1786 g/L at room temperature.

My element Iron, is a pretty dense metal. The formula for calculating density, Mass divided by Volume or D= M/ V, is used for Iron. The mass is measured in Grams and the volume is measured in Cubic Centimeters. The density of any type of element is constant. The density of Iron is 7.874 g/ cc.

To find the density of an object you use the equation mass/volume=density.

The density of lead is 11.35 g/cm3.

Density is defined as the ratio of a material’s mass to its volume.  Discovered by a German chemist Martin Heinrich Klaproth in 1789, uranium is one of the denser metals that can be found on the periodic table of the elements. Its density is approximated to be 19,050 kg/m^3. Uranium is about 19 grams per cubic centimeter, it is 1.6 times more dense than lead. Density increases weight.

Calcium is a solid that is weighted by grams. The density of calcium is 1.55 g/cm³ (1.55 g/mL). The scientist uses Mass divided by Volume to determine the density.

The density of Titanium is 4.506 g/cm³

This formula for its density is D= M/V

Scientist determine my element of mercury’s density by taking its weight, in grams, by its volume in cc or mL. Its mass is 200.59 and the volume is 20 cc. The density of mercury in this case is 10.0295, and in significant figures, just 10.

Density is equal to mass/volume.

The density of iodine is 4.933 g/cm^3.
