Answer:
The weight% of
in augite is 13.16 %.
Explanation:
Atomic mass of calcium = 40 g/mol
Atomic mass of iron = 56 g/mol
Atomic mass of magnesium = 24 g/mol
Atomic mass of sodium = 23 g/mol
Atomic mass of aluminum = 27 g/mol
Atomic mass of silicon = 28 g/mol
Atomic mass of oxygen = 16 g/mol
Mass of ![SiO_2=28 g/mol+ 2\time 16 g/mol=60 g/mol](https://tex.z-dn.net/?f=SiO_2%3D28%20g%2Fmol%2B%202%5Ctime%2016%20g%2Fmol%3D60%20g%2Fmol)
Molar mass of the augite
= M
![M=40 g/mol+2\times 56 g/mol+2\times 24 g/mol+23 g/mol+3\times 27 g/mol+2\times 28 g/mol+6\times 16 g/mol=456 g/mol](https://tex.z-dn.net/?f=M%3D40%20g%2Fmol%2B2%5Ctimes%2056%20g%2Fmol%2B2%5Ctimes%2024%20g%2Fmol%2B23%20g%2Fmol%2B3%5Ctimes%2027%20g%2Fmol%2B2%5Ctimes%2028%20g%2Fmol%2B6%5Ctimes%2016%20g%2Fmol%3D456%20g%2Fmol)
Weight% of
in augite:
![w\%=\frac{60 g/mol}{456 g/mol}\times 100=13.16\%](https://tex.z-dn.net/?f=w%5C%25%3D%5Cfrac%7B60%20g%2Fmol%7D%7B456%20g%2Fmol%7D%5Ctimes%20100%3D13.16%5C%25)
Mt. Vesuvius is A VOLCANIC MOUNTAIN.
It was famously known for causing the fires of Pompeii and killing millions of people.
Mt. Vesuvius, a cone-shaped mountain is part of the Campainian Volcanic Arc. It has erupted 30 times as recorded by scientists. It is currently considered as one of the top ten most dangerous volcanoes of the world.
Answer: For instance, plants (biosphere) grow in the ground (geosphere), but to survive they absorb water (hydrosphere) and carbon dioxide (atmosphere). Nor are plants merely absorbing: they also give back oxygen to the atmosphere, and by providing nutrition to animals, they contribute to the biosphere.
Hope this helps...... Stay safe and have a Merry Christmas!!!! :D
