Calculate the density of mercury if 1.00x10^2g occupies a bolume of 7.36 cm

Taking into account the definition of density, the density of mercury is 13.59 .

First you have to know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.  This is, density is the relationship that exists between the mass of a substance (or a body) and its volume.

It is an intrinsic property of matter because it does not depend on the amount of substance that is considered.

The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

In this case, you know that:

Replacing in the definition of density:

Solving:

density= 13.59

Finally, the density of mercury is 13.59 .

13.6g/cm³

Explanation:

To calculate density of mercury we divide the mass by the volume.

1.00 × 10²g ÷ 7.36cm³ = 13.6g/cm³

The concentration of SO₂ will decreases

Explanation:

As you can see in the reaction

2 moles of gas ⇆ 3 moles of gas

Based on Le Châtelier's principle, a change doing in a system will produce that the system reacts in order to counteract the change made.

If the pressure is increased, the system will shift to the left in order to produce less moles of gas and decrease, thus, the pressure.

As the system shift to the left, the concentration of SO₂ will decreases
