The answer is either platinum or chengdeite depending on who you believe. Meaning, chengdeite has a specific gravity listed at various places as between 19 and 20, whereas others list pure platinum is listed between 18 and 20+. The reality is that there are some denser minerals that are enriched with iridium and/or osmium. Iridium, which is named after the element but usually, if not always, contains other elements as well, is the most dense (22.65) if you include enriched minerals. After reading much on the subject, I suspect that platinum is the best answer because chengdeite is extremely rare and therefore not enough has been measured to come to a conclusive determination of its mean specific gravity. There wouldn't be a need for this if chengdeite were a true element, but though it is classified as an element, in chemical reality it is an alloy, so the specific gravity can vary (presumably slightly, but there's not enough to say for sure) from piece to piece. The number represents weight in grams per cubic centimeter.

What is the least accurate way to identify a mineral?
The observable color is the least dependable method of mineral identification.
Which mineral property is the least reliable for identifying a mineral?
Color is the least reliable property for identifying a mineral because many minerals can have the same color but different compositions.
Least accurate way to identify a mineral?
the least accurate way to identify a mineral
What mineral property is the least useful property?
Luster is typically considered the least useful mineral property, as it does not provide much information about the mineral's identity or composition. Luster simply describes how light is reflected off the surface of a mineral, such as metallic, glassy, or dull, and can vary even within the same mineral species.
What is less dense water basalt iron or granite?

Is Earth the least dense of all planets?
No. In fact it is the most dense planet. The least dense is Saturn.
What is the dense part of the earth?
One could say that the atmosphere is the least dense, but of the surface the crust is the least dense.
Which is the least dense?
Helium is the least dense element at normal conditions.
Is cotton least dense?
'Least' is a comparison word. Compared to iron and lead yes cotton is least dense. Compares to oxygen gas and hydrogen gas, no it is not least dense.
What gas is the most or least dense when heated?
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
The least dense of all planets?
Saturn is the least dense planet in our solar system.
What part of the atmosphere is least dense?
The exosphere is the least dense part of the earth's atmosphere.

What is the least dense of the Galilean moons?
Callisto is composed of rock and ice and is the least dense of the Galilean moons.
What is least dense?
Lithium
What is the least dense crust outer core mantle or the inner core?
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense
