Answer:

46.5

explanation

6.022*10^23 molecules=40g.

7.00*10^23=40*7.00*10^23/6.022*10^23 g =46.5 g

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, 4.65g  are  7.00 x 10²²  molecules of NaOH.

The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms of NaOH= 7.00 x 10²² atoms

Substituting the values

mole=7.00 x 10²²÷ 6.022×10²³

mole =0.116 moles of NaOH

mass of NaOH= Molar mass of NaOH× moles of NaOH

= 40 × 0.116

= 4.65g

Therefore, 4.65g are  7.00 x 10²²  molecules of NaOH.

Answer:

So your Circle equals 360 so what i did was 360-108 and got 252 now if you do 360-252 it will equal 252 don't know if this help but.

Answer:

Point above the line is an outlier

Step-by-step explanation:

If the point is above the given line then it is clear that it does not fit the best fit curve (which is in this case is the line represented by equation y=4.413x+0.377)  

Point above this line means that the point is an outlier which does not fit the curve.

Answer:

I think its a bc I took ze test and its right

Step-by-step explanation:

Sorry if its wrong

===================================================

Work Shown:

1 liter = 1000 milliliters

1 spoon = 5 milliliters

200*(1 spoon) = 200*(5 milliliters)

200 spoons = 1000 milliliters

200 spoons = 1 liter

Notice how 1000/5 = 200, so that's why I multiplied both sides of the second equation by 200 to end up with what is shown above.

Answer:

G = 46 degrees

Step-by-step explanation:

Here, we want to find the measure of angle G

Mathematically, as we can see, what we have is a right triangle

For a right triangle , the sum of angles is 90 degrees

Thus, if we add the two internal angles, we get 90 degrees

Hence;

44 + G = 90

G = 90-44

G = 46 degrees

Answer:

There are 4 boys for every 6 girls (4 : 6 ratio)

Answer:

18π cm²

Step-by-step explanation:

The area of the shaded region = Area of Sector

Radius, r =

The value of θ = 80°

Recall :

Area of Sector :

A = θ / 360 * πr²

A = (80 / 360) * π * 9²

A = 0.222222 * π * 81

A = 18π cm²

The slope-intercept form of an equation for the line of fit shown in the scatter plot is; C. y=1.13x-2233.63

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.

We can observe that the line of best fit on this scatters plot passes through points (1997, 13) and (2005, 22).

Using the slope formula,

⇒ slope = (22 - 13)/(2005 - 1997)

⇒ slope = (9)/8

Also, the slope-intercept form of an equation for the line of fit shown in the scatter plot is;

y - 13 = (9)/8(x - 1997)

y = 1.13x  -2233.63

Therefore, the slope-intercept form of an equation is y = 1.13x  -2233.63
