An unknown metal cylinder has a mass of 34.3 g and a volume of 2.1 mL . What is the density of the metal in g / m * L ?

saul85 [17]

Taking into account the definition of density, the density of the metal is 16.33 $\frac{g}{mL}$ .

<h3>Definition of density</h3>

Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance. Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

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

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.

<h3>Density of the metal in this case</h3>

In this case, you know that:

Mass= 34.3 g
Volume= 2.1 mL

Replacing in the definition of density:

$density=\frac{34.3 g}{2.1 mL}$

Solving:

<u><em>density= 16.33 </em></u> $\frac{g}{mL}$

In summary, the density of the metal is 16.33 $\frac{g}{mL}$ .

As carbon dioxide (CO2) changes from its solid state to gaseous state, what happens to the energy and motion of the particles?

SVEN [57.7K]

1) As carbon dioxide changes from solid state to gaseous state, the particles gain energy and move faster.

The molecule of CO2 gain energy which results in greater separation of each other and freer and faster movement

2) When a substance undergoes a change of state its mass does not change

if 4.12 L of 0.85-M H3PO4 solution is be diluted to a volume of 10.00 L,what is the concentration resulting solution

Alja [10]

Answer:

The concentration resulting solution = 0.350 M

Explanation:

In case of dilution , the following formula can be used -

M₁V₁ = M₂V₂

where ,

M₁ = initial concentration ,

V₁ = initial volume ,

M₂ = final concentration , i.e. , concentration after dilution ,

V₂ = final volume .

from , the question ,

M₁ = 0.85 M

V₁ = 4.12 L

M₂ = ?

V₂ = 10.0 L

Using the above formula , the molarity of the final solution after dilution , can be calculated as ,

M₁V₁ = M₂V₂

0.85 M * 4.12 L = M₂ * 10.0 L

M₂ = 0.85 M * 4.12 L / 10.0 L

M₂ = 0.350 M
