Answer:
2 moles
Explanation:
Let us first start by calculating the molecular mass of Al₂O₃.
The mass of a mole of any compound is called it's molar mass. 1 molar mass 6.02 X 10²³, or Avogadro's number, of compound entities.
Say, 1 mole of Al₂O₃ has 6.02 X 10²³ of Al₂O₃ molecules/atoms. It also has 2*6.02 X 10²³ number of Al atoms and 3*6.02 X 10²³ number of O atoms.
Molecular mass of Al : 26.981539 u
Molecular mass of O: 15.999 u
Therefore, molecular mass of Al₂O₃ is:
= 
u
= 101.960078 u
This can be approximated to 102 u.
1mole weighs 102 u
So, 2moles will weigh 2*102 = 204 u
The correct answer is A. The conservationist credited with founding the Wilderness Society is Bob Marshall.
Bob Marshall was an American forester, botanist, traveler, climber, writer and social activist who advocated the preservation of unspoiled wildlife.
He actively contributed to the development and adoption of environmental regulations prohibiting the construction of roads in vast federal specially protected natural areas. In 1935 he became one of the founders of the public environmental organization The Wilderness Society and its main sponsor.
Today Bob Marshall is considered one of the main initiators of the wildlife movement in the United States. Several geographic features are named after him, including the Bob Marshall Wilderness Nature Reserve in Montana and the Marshall Mountain on the Adirondack Ridge.
