1st part.)). The rest of the water goes into oceans and underground.
1. First calculate the total molar mass of the entire compound.
Mg = 3 x 24.31 = 72.93 g/mol
P = 2 x 30.97 = 61.94 g/mol
O = 8 x 16.00 = 128.00 g/mol
* Add them up;
72.93 + 61.94 + 128.00 = 262.87 g/mol
2. Take the individual masses of each element that you calculated, divide them by the total mass (262.87 g/mol) and then multiply by 100.
Mg = 72.93/262.87 = 0.2774 x 100 = 27.74%
P = 61.94/262.87 = 0.2356 x 100 = 23.56%
O = 128.00/262.87 = .4870 x 100 = 48.70%
3. All of the percentages should add up to equal 100%.
* Hope this helps
Answer:
Fossils are essentially clues that have been left behind by various forms of living things. They are instrumental tools for understanding the diverse groups of organisms that have inhabited our planet at one time or another. A fossil is any preserved evidence of an organism.
