If a particular ore contains 55.0 %% calcium phosphate, what minimum mass of the ore must be processed to obtain 1.00 kgkg of phosphorus?

PHOSPHOROUS...METAL OR NONMETAL? Phosphorous is highly reactive and never found as a free element on Earth. It can be found as white phosphorous and red phosphorus. White phosphorous is the more common form and, as the name suggests, is a white, waxy substance. White phosphorous emits a glow when exposed to oxygen, which is where the name Phosphorous come from. In Greek, phosphorous means "light bearer". Phosphorous is essential for life, where it is found in DNA, RNA, and ATP as well as the phospholipids which make up our cell membranes. Phosphorous is used by plants and thus fertilizer is used to replace phosphorous in the soil. Since phosphorous is so reactive it is even added to Napalm but more commonly you can find phosphorous in matches, where it is bonded to sulfur, which makes the head of a match much safer. White phosphorous melts at 44.1°C and boils at 280°C. It combines readily with chlorine and other halogens. Since it is so reactive it is stored under water in chemical…
