Yes this is true.
Oxygen comprises about 47% by weight of Earth's crust
The Earth's crust contains eight elements. The most common element among the eight is Oxygen (47 percent) and second is Silicon (28 percent).
47 % oxygen & 27% silicon.
obviously something but not known what!
The Earth's crust contains eight elements. The most common element among the eight is Oxygen (47 percent) and second is Silicon (28 percent).
you say 47 percent of this has, or 47 percent of these have.
47 percent out of 100 percent is 47 percent (0.47 x 100 percent = 47 percent). More clearly, 47 % / 100 % = 47 / 100 = 0.47
(NH4)2S % Nitrogen = 41.2 % % Hydrogen = 11.8 % % Sulphur = 47 %
The Earth's crust contains eight elements. The most common element among the eight is Oxygen (47 percent) and second is Silicon (28 percent).
Oxygen is the most abundant element in Earth's crust, making up about 47% of its mass. Silicon is the second most abundant element, comprising approximately 28% of the crust's mass.
Earth contains 21 percent of oxygen in the atmosphere!coz earth contains only hot gases and oxygen is not a hot gas!:D
47 in percent form = 4700%47 * 100% = 4700%
