What material makes up ash and pumice?

1 answer:

7 0

Pumice rocks are formed due to the air that is trapped in between the rocks, a body of magma spurting out with dissolved gas under pressure. As the magma cracks through the Earth’s surface, the sudden pressure drop causes the gas to come out of the solution. The flash of gas form the vent slices the magma and blows it out as a molten lather. The lather hastily solidifies as it flies into the air and falls back to Earth as pieces of pumice.

An organic solvent has a density of 1.31 g/mL. What volume is occupied by 57.5 g of the liquid?

Burka [1]

Answer:

<h3>The answer is 43.89 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass = 57.5 g

density = 1.31 g/mL

We have

$volume = \frac{57.5}{1.31} \\ = 43.89312977...$

We have the final answer as
