The density of concentrated nitric acid (HNO3) is 1.413 g/mL. What volume in liters would be occupied by a mass of 47.2 g?

DerKrebs [107]

Answer:

The volume that a mass of 47.2 g would occupy is 0.0334 L

Explanation:

Density is the property that matter, whether solid, liquid or gas, has to compress into a given space. Density is defined as the amount of mass it has per unit volume, that is, the ratio between the mass of a body and the volume it occupies:

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

This indicates that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

In this case:

density= 1.413 g/mL
mass= 47.2 g
volume=?

Replacing:

$1.413 \frac{g}{mL}=\frac{47.2 g}{volume}$

Solving:

$volume=\frac{47.2 g}{1.413\frac{g}{mL} }$

volume=33.40 mL

Being 1,000 mL= 1 L:

volume= 0.0334 L

<u><em> The volume that a mass of 47.2 g would occupy is 0.0334 L</em></u>

Prove that the liquid pressure is directly proportional to the depth of the liquid?

Free_Kalibri [48]

Explanation:

Pressure and depth have a directly proportional relationship. This is due to the greater column of water that pushes down on an object submersed.. so the deeper the liquid level the higher the pressure of the liquid.

Nimfa-mama [501]

Answer:

A compound

Explanation:

Chemical compound can be regarded as any substance made up of identical molecules which consists atoms of two or more than two chemical elements. For example four hydrogen atoms bonds with a carbon atom to give methane molecule which is a compound. It should be noted that A compound is a new substance with unique chemical and physical properties formed when two or more elements are chemically bonded during a physical reaction.
