The volume of gasoline (in cubic centimeters) is \boxed{0.029\;\text{cm}^3}.

Further Explanation:

Density is defined as the mass of the substance per unit volume of the substance. It is denoted by \rho. It is generally expressed in the units of grams per cubic centimeter (\text{g/cm}^3). The formula to calculate the density of a substance is as follows:

\rho=\dfrac{\text{M}}{\text{V}}  

Here,

\rho is the density of the substance.

M is the mass of the substance.

V is the volume of the substance.

The formula to calculate the density of gasoline is as follows:

\text{Denstiy of gasoline}=\dfrac{\text{Mass of gasoline}}{\text{Volume of gasoline}}                                                             …… (1)

Rearrange equation (2) to calculate the volume of gasoline.

\text{volume of gasoline}=\dfrac{\text{Mass of gasoline}}{\text{Density of gasoline}}             …… (2)                                              

The mass of gasoline is 22 mg. This is to be converted into g. The conversion factor for this is,

1\;\text{mg}=10^{-3}\text{g}  

Therefore the mass of gasoline can be calculated as follows:

 \begin{aligned}{\text{Mass of gasoline}}&= \left( {22{\text{ mg}}} \right)\left( {\frac{{{{10}^{ - 3}}{\text{ g}}}}{{1{\text{ mg}}}}} \right)\\&= 0.022{\text{ g}} \\ \end{aligned}

The mass of gasoline is 0.022 g.

The density of gasoline is 0.754\;\text{g/cm}^3.

Substitute these values in equation (2).

 \begin{aligned}\text{Volume of gasoline}&=\frac{0.022\;\text{g}}{0.754\;\text{cm}^3}\\&=0.029\text{cm}^3\\\end{aligned}

Therefore the volume of gasoline is 0.029\;\text{cm}^3.

<em><u>Answer:</u></em>

volume = 0.029 cm³

<em><u>Explanation:</u></em>

<u>We are given that:</u>

mass = 22 mg

<u>We know that:</u>

1 mg = 0.001 grams

<u>This means that:</u>

mass = 22 mg = 0.022 grams

<u>We are also given that:</u>

density = 0.754 g/cm³

<u>Density is calculated using the following rule:</u>

Density=\frac{mass}{volume}

<u>Rewrite the equation to solve for volume:</u>

volume = \frac{mass}{density}

<u>Now, substitute with the values we have:</u>

volume = \frac{0.022}{0.754} = 0.029 cm^3

Hope this helps :)

Which of the following samples contains the greatest number of atoms?
mart [117]

Answer:

C. 11 moles of N2O

Explanation:

A. CO2 exists as a molecular compound. The number of atoms present = 1 atom of Carbon and 2 atoms oxygen = 3 atoms * 9 = 18 atoms

B. Xe exists as an atom. Number of atoms present = 10 * 1 atom = 10 atoms

C. N20 contains 3 atoms; 2 atoms of Nitrogen and 1 atom of oxygen.

Number of atoms present = 3 * 11 = 33 atoms

D. CO contains 2 atoms, 1 each of carbon and oxygen.

Number of atoms present = 12 * 2 = 24 atoms

The standard cell potential Ec for the reduction of silver ions with elemental copper is 0.46V at 25 degrees celsius. calculate
Cloud [144]

Answer : The \Delta G for this reaction is, -88780 J/mole.

Solution :

The balanced cell reaction will be,  

Cu(s)+2Ag^+(aq)\rightarrow Cu^{2+}(aq)+2Ag(s)

Here, magnesium (Cu) undergoes oxidation by loss of electrons, thus act as anode. silver (Ag) undergoes reduction by gain of electrons and thus act as cathode.

The half oxidation-reduction reaction will be :

Oxidation : Cu\rightarrow Cu^{2+}+2e^-

Reduction : 2Ag^++2e^-\rightarrow 2Ag

Now we have to calculate the Gibbs free energy.

Formula used :

\Delta G^o=-nFE^o

where,

\Delta G^o = Gibbs free energy = ?

n = number of electrons to balance the reaction = 2

F = Faraday constant = 96500 C/mole

E^o = standard e.m.f of cell = 0.46 V

Now put all the given values in this formula, we get the Gibbs free energy.

\Delta G^o=-(2\times 96500\times 0.46)=-88780J/mole

Therefore, the \Delta G for this reaction is, -88780 J/mole.

Describe the three main types of plate boundary interactions:
bulgar [2K]

Answer:

In the explanation

Explanation:

Divergent: When two plates are diverging from each other, meaning that the two plates are moving away from each other. Events that may occur include ridges or rifts.

Convergent: When two plates are moving towards each other.

If a continental plate and an oceanic plate are converging, the oceanic plate would slide underneath the continental plate since it is thinner. This would result in subduction, which means that part of the oceanic plate would hang underneath the continental plate, where magma can melt the hanging part.

If two continental plates are converging, the crash would result in mountains or volcanic activity. Magma could rise and rush from the crack. There would be a bump in these tectonic plates.

Transform: When two plates are sliding past each other. Earthquakes can occur when the plates are sliding. When an oceanic plate is involved, the movement of the plates could cause a tsunami as well. The water above the transform fault could rise, and grow bigger and bigger. The 2011 Japan Tsunami is a good example of this.

Hope this helps!
