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 :)

The model of a “sea of electrons” helps explain ____.
andriy [413]

Answer:

The correct answer is C.) metallic bonds

Explanation:

Metallic bonds are formed between metal compounds and are very strong. These links are explained by the "sea model of electrons", where valence electrons are ceded by each metal atom, becoming positive ions forming a three-dimensional crystalline network. These electrons move forming a network ("sea") that allows the union of the positive ions formed.

If you dilute 19.0 mL of the stock solution to a final volume of 0.310 L , what will be the concentration of the diluted solutio
Dahasolnce [82]

Answer:

M_2=0.613M_1

Explanation:

M_1 = Concentration of stock solution

M_2 = Concentration of solution

V_1 = Volume of stock solution = 19 mL

V_2 = Volume of solution = 0.31 L= 310 mL

We have the relation

M_1V_1=M_2V_2\\\Rightarrow M_2=\dfrac{M_1V_1}{V_2}\\\Rightarrow M_2=\dfrac{M_119}{310}\\\Rightarrow M_2=M_1\times\dfrac{19}{310}\\\Rightarrow M_2=0.613M_1

\boldsymbol{\therefore M_2=0.613M_1}

The concentration of the diluted solution will be 0.613 times the concentration of the stock solution.
