<em> The amount to donate is 1,015.10⁸  </em>

\boxed{\boxed{\bold{Further~explanation}}}  

In mathematical calculations, the symbol of percent is used  

The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)  

Formula used:  

\large{\boxed{\bold{Percentage\:=\:\frac{Total\:Section}{Total\:Amount}\:\times\:100\percent}}}

Fractions either ordinary or mixed (consisting of numerators and denominators) or decimal forms can we change to a percentage  

The percentage can be expressed as a decimal by moving the decimal point two places to the left

One way to convert ordinary fractions to percent forms (The easiest way) is to multiply the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number.

<em>Known Variable  </em>

(0.125%) of her new net worth (8.12 * 10 ^ 10 to charity.  

<em>Variables that are asked  </em>

dollars are given to charity?  

<em>The answer  </em>

The desired percentage to donate from the number 8,12 .10¹⁰ is 0.125% so the amount is:  

0.125% x 8,12 10¹⁰ = 101500000 = 1,015.10⁸

ANSWER: $101,500,000

EXPLANATION: The individual's net worth is 8.12 X 10^{10} .

To find the dollars donated to charity from the individual's net worth which will be one eight percent;

We can use the following method;

By simply multiplying the one eighth (0.125) percent with the new net worth we can get the answer.

0.125 X 8.12 X 10^{10} = $101,500,000

Therefore, the amount donated by the individual in dollars was $101,500,000.

A graduated cylinder contains 18.0ml of water. what is the new water level after 35.6g of silver metal with a density of 10.5 g/
AlekseyPX

Answer:

The answer to your question is

1.- Volume = 3.4 ml

2.- Volume = 0.61 ml

3.- Mass = 2872.8 pounds

Explanation:

Problem 1

Volume = 18 ml

mass = 35.6 g

density = 10.5 g/ml

Process

1.- Calculate the volume of silver

Formula

density = \frac{mass}{volume}

solve for volume

volume = \frac{mass}{density}

Substitution

volume = \frac{35.6}{10.5}

<u>volume = 3.4 ml</u>

2.- Problem 2

Total volume = ?

Volume = 18 + 3.4

Volume = 21.4 ml

Data

mass = 8.3 g

density = 13.6 g(ml

volume = ?

Formula

density = \frac{mass}{volume}

Solve for volume

volume = \frac{mass}{density}

Substitution

volume = \frac{8.3}{13.6}

Result

<u>volume = 0.61 ml</u>

3.- Problem 3

Data

volume = 345 gal

density = 1 g/ml

mass = ?

Formula

density = \frac{mass}{volume}

Solve for mass

mass = density x volume

Covert gal to ml

                            1 gal --------------- 3785 ml

                         345 gal -------------  x

                            x = (345 x 3785) / 1

                            x = 1305825 ml

Substitution

mass = 1 x 1305825

mass = 1305825 g

Convert g to pounds

                        1 g ------------------- 0.0022 pounds

              1305825 g ----------------   x

                        x = (1305825 x 0.0022)

                       <u> x = 2872.8 pounds</u>

Convert mass to moles for both reactants. (round to 2 significant figures.) 2.50 g cuci2 equals moles e 0.25 g Al equals moles D
Marat540 [252]
To convert a mass of a substance to units of moles, we would need the molar mass of the substance since is it describes the mass of one mole of that substance. For CuCl2, the molar mass is 134.45 g/mol. For Al, the atomic mass is 26.98 g/mol.

2.50 g CuCl2 ( 1 mol / 134.45) = 0.019 mol CuCl2
0.25 g Al ( 1 mol / 26.98 g ) = 0.0093 mol Al

Based on the information, what is the balanced chemical equation representing the burning of butane?
kompoz [17]

Answer:

OptionA. 2C4H10 + 13O2 —> 8CO2 + 10H20

Explanation:

Butane burns is air (O2) according to the equation:

C4H10 + O2 —> CO2 + H20

Considering the equation, it is evident that it not balanced. Now let us balance the equation as shown below;

There are a total of 4 carbon atoms on the left and 1 carbon atom on the right. It can be balanced by putting 4 in front of CO2 as shown below:

C4H10 + O2 —> 4CO2 + H20

Next, there are 10 hydrogen atoms on the left and 2 hydrogen atoms on the right. Therefore to balance it, put 5 in front of H2O as shown below:

C4H10 + O2 —> 4CO2 + 5H20

Now, there are a total of 13 oxygen atoms on the right and 2 at the left. To balance it, put 13/2 in front of O2

as shown below

C4H10 + 13/2O2 —> 4CO2 + 5H20

Now we multiply through by 2 clear off the fraction and we obtained:

2C4H10 + 13O2 —> 8CO2 + 10H20

The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant
Elena-2011 [213]

Answer:

20 atm / (R . 321 K . i) = M

Explanation:

Osmotic pressure is a colligative property which is determined by the solute.

Solutes over solutions, can increase the osmotic pressure which is calculated like this:

P = M . R . T

where P is pressure, M is molarity, R the Universal Constant Gases and T, the absolute Temperature. We also have to consider the Van't Hoff factor, i, numbers of ions dissolved. Ionic salts determine more osmotic pressure than organic compounds, where i = 1. Then, the complete formula is:

π =  M . R . T . i

To determine molarity, osmotic pressure divide all the terms:

20 atm / (R . 321 K . i) = M

R = 0.082 L.atm/mol.K

If you see all the units in R, they will be cancelled, so finally the answer will be mol/L, which is molarity. The i term has no unit!.
