Answer: 0.0450 moles of 
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number 
of particles.

Thus there are 0.0450 moles of
Answer:
moving bits of rock and soil across the earth’s surface by water, wind, or glaciers
Explanation:
Erosion is the active wearing away of the earth's surface by agents of denudation such as running water, wind, ice and waves.
Denudation is the process of lowering and leveling of the earth surface by gradual breaking and wearing away of the earth.
The sequence of denudation progresses from weathering to erosion through transportation and it finally ends with depositions.
Erosion moves rock bits and soils that have been disintegrated and decayed by the process of weathering. During transportation, eroded materials are carried away to new areas where they are deposited.
