Another statement is, "Volume is directly proportional to the number of moles."

The volume increases as the number of moles increases. It does not depend on the sizes or the masses of the molecules.

V

V

is the volume, and

n

is the number of moles.

V

We can rewrite this as

Equal volumes of hydrogen, oxygen, or carbon dioxide contain the same number of molecules.

STP is 0 °C and 1 bar.

One mole of an ideal gas occupies 22.71 L at STP. Thus, its molar volume at STP is 22.71 L

Example Problem

A 6.00 L sample at 25.0 °C and 2.00 atm contains 0.500 mol of gas. If we add 0.250 mol of gas at the same pressure and temperature, what is the final total volume of the gas?

Answer:

To find the slope, use the formula rise/run or change in y/change in x

In this case, the slope is 5

To find y-intercept, substitue  values for x and y

Step-by-step explanation:

-3 = 5(2) + b

-3 = 10 + b

-10    -10  

-13 = b

Therefore, b is -13

So here's how the equation looks in slope-intercept form

Answer:

Width: 4 meters. Length: 11 meters

Step-by-step explanation:

If you do it correctly, the length should be 3 more greater than 4*2. 4*2= 8 +3= 11. Your perimeter= 30 meters. 11+11 accounting for both long sides of the rectangle= 22. Accounting for both sides of the width, so 4*2=8 + our 22= 30 meters. Yw.

The length of the rectangle​ width 4 meters and length 11 meters.

If you do it correctly,

The length should be 3 more greater than

P=2(l+w)

L= Length

W = Width

4*2. 4*2= 8 +3= 11.

Your perimeter= 30 meters.

11+11 accounting for both long sides of the rectangle= 22.

Accounting for both sides of the width,

So 4*2=8 + our 22= 30 meters.

Therefore we get the length of a rectangle is  11 meters.

Answer:

BC ≈ 98.95 feet

Step-by-step explanation:

From the figure attached,

A shark is swimming 42 feet below sea level at point A and a boat on the water is at point C.

If the angle of depression from the coat to shark is 23°,

tan(23°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(23°) = [tex]\frac{AB}{BC}[/tex]

BC = [tex]\frac{AB}{\text{tan}(23)}[/tex]

BC = [tex]\frac{42}{\text{tan}23}[/tex]

BC = 98.947

BC ≈ 98.95 feet

Step-by-step explanation:

Domain: 0<x<3.5

To get 3.5:  7/2=3.5

Negatives and decimals can't be used

Approximate maximum volume for this box?  55

The proper domain of Noah's graph should be 0 to 3.5 and the maximum of the graph is at y = 60.

It is required to find the approximate maximum volume for his box.

Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.

Given:

From the attached graph (see attachment), we have the following observations:

1.The x values starts from -1 and ends at 60

2.The domain of the graph is from 0 to 4 (i.e. x-values 0 to 4 have corresponding y-values on the graph)

3.x-values 0 to 3.5 have corresponding non-negative y-values

4.Other values of x have corresponding negative y-values

5.The maximum of the graph is at y = 60

Because the volume of a box cannot be negative, the x-values to use must correspond to non-negative y-values.

Hence, the proper domain of Noah's graph should be 0 to 3.5 and the maximum of the graph is at y = 60.

Answer:

B

Step-by-step explanation:

We want the equation of the line that passes through the point (-1, 1) and is perpendicular to:

[tex]2x +4y=16[/tex]

Remember that the slopes of perpendicular lines are negative reciprocals of each other.

So, let's find the slope of the original line first. We can do so by converting it to slope-intercept form. Thus:

[tex]4y=-2x+16[/tex]

Therefore:

[tex]\displaystyle y=-\frac{1}{2}x+4[/tex]

The slope is -1/2.

The negative reciprocal of -1/2 is 2.

Thus, the slope of our new line is 2.

The slope is 2 and it passes through the point (-1, 1).

We can use the point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

Substitute:

[tex]y-(1)=2(x-(-1))[/tex]

Distribute:

[tex]y-1=2x+2[/tex]

Subtracting 2 from both sides yields:

[tex]y-3=2x[/tex]

Therefore, our answer is B.

Answer:Average speed =50 miles per hour or 50mph

Step-by-step explanation:

We know that  Speed is given as= Distance/ Time

Nimer's  distance to his destination = 65 miles

Time taken to his destination = 13:30 to  14:48

which is = 14:48--13:30 = 1:18 mins

Converting  1hr 18mins  to hours = 1 hour + 18/ 60 = 1 + 0.3 = 1.3 hours

Average speed =Distance/ Time

Average speed = 65miles/ 1.3hr = 50 miles per hour
