Answer:

The number of mole represented is 2.07 moles

Explanation:

Using the formula

n = m/Mm

n - mole

m - mass

Mm- molar mass

Since the mass is given to be 213g

So lets calculate the molar mass of sodium bromide (NaBr)

The molar mass of Na = 22.99

Br = 79.904

Molar mass = 22.99+79.904

= 102.894g/mol

Using the formula n = m/Mm

n = 213g/ 102.894g/mol

n = 2.07moles

Masja [62]

The earth's mantle will not change in the future because this region is safe from the intervention of human beings.

<h3>What happens in the Earth's mantle?</h3>

The transfer of heat and material in the mantle helps us to determine the landscape of Earth. Activity in the mantle moves the plate tectonics, that contributes to volcanoes, seafloor spreading, earthquakes, and building of mountains.

So we can conclude that the earth's mantle will not change in the future because this region is safe from the intervention of human beings.
