Answer: C.   146 g

Explanation:

To calculate the moles, we use the equation:

\text{Number of moles}=\frac{\text{ mass}}{\text{Molar mass}}  

Thus  Mass=\text{Number of moles}\times {\text{Molar mass}}  

For sodium nitrate (NaNO_3)

moles = 1.72

Molar mass of sodium nitrate  (NaNO_3)= 85g/mol

Putting values in above equation, we get:

Mass=1.72moles\times 85g/mol=146g

Explain how earth plates and lithosphere are related
AnnyKZ [126]

Crust, the upper layer of the Earth, is not always the same. Crust under the oceans is only about 5 km thick while continental crust can be up to 65 km thick. Also, ocean crust is made of denser minerals than continental crust.

The tectonic plates are made up of Earth’s crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep. The lithosphere is broken into giant plates that fit around the globe like puzzle pieces. These puzzle pieces move a little bit each year as they slide on top of a somewhat fluid part of the mantle called the asthenosphere. All this moving rock can cause earthquakes.

The asthenosphere is ductile and can be pushed and deformed like silly putty in response to the warmth of the Earth. These rocks actually flow, moving in response to the stresses placed upon them by the churning motions of the deep interior of the Earth. The flowing asthenosphere carries the lithosphere of the Earth, including the continents, on its back.
