What is the density of the oceanic crust?

Besides, what is the density of the oceanic plate?
Differences in Density The average density of ocean plates is approximately 200 pounds per cubic foot, while continental crust ranges between about 162 and and 172 pounds per cubic foot. This difference in relative density causes oceanic plates to subduct beneath the more buoyant continental plates.
Also Know, what is oceanic crust made of? The oceanic crust, which, on average, is only about six kilometers thick, is primarily made up of the igneous rock basalt. Basalt tends to come from lava that flows smoothly and quietly from a volcanic vent, unlike the viscous lava typical of the violent eruptions of many continental volcanoes.
Besides, why is the oceanic crust more dense?
Oceanic crust is denser, so it is subducted (see above) under the continental crust. The less dense magma rises up through the continental crust, further increasing the size of the continental crust and maintaining its lower density than the oceanic crust, which causes subduction.
