1)What is the mass of Nitrogen in NH3? (use two decimal places)
Mars2501 [29]

Answer:

1)  The Mass of Nitrogen in NH_3 is<u> 14.00 gm.</u>

2) The Mass of Hydrogen in NH_3 is<u> 3.00 gm.</u>

3<u>)</u>The Molar Mass of NH_3 is <u>17.00 gm.</u>

Step-by-step explanation:

Solving for Part 1.

In NH_3 that is Ammonia there is 1 atom of Nitrogen.

So the atomic mass of Nitrogen is same as the mass of Nitrogen in NH_3.

Atomic mass of Nitrogen = 14.00 gm

Hence The Mass of Nitrogen in NH_3 is<u> 14.00 gm.</u>

<u />

Solving for Part 2.

In NH_3  there are 3 atoms of Hydrogen.

Atomic mass of Hydrogen = 1.00 gm

So the mass of Hydrogen in  NH_3 is 3 times of its atomic mass.

Mass of Hydrogen = 3 × Atomic mass of Hydrogen

Mass\ of\ Hydrogen =3\times1.00=3.00\ gm

Hence The Mass of Hydrogen in NH_3 is<u> 3.00 gm.</u>

<u />

Solving for Part 3.

In NH_3  there is 1 atom Nitrogen and 3 atoms of Hydrogen.

So molar mass is the sum of mass of nitrogen and mass of Hydrogen in NH_3.

Molar mass of NH_3=Mass of Nitrogen+Mass of Hydrogen

Molar\ mass\ of\ NH_3=14.00+3.00=17.00\ gm

Hence The Molar Mass of NH_3 is <u>17.00 gm.</u>

Which function is represented by the graph below? graph begins in the second quadrant near the x−axis and increases slowly while
VLD [36.1K]
This seems an exponential function.

Once you state that the function is exponential you can write is this form:

f(x) = A * b^x.

Then you need the y-intercept (i.e. x = 0) to find A

f(0) = A * b^0 = A

Once you have A, you can use the ordered pair (3,1) to find b

f(1) = A*b^2 = A*b = 3 => b = 3/A.

With that procedure you can find the function that represents the given graph.

Suppse the y-intercep is 0.1

Then f(0) = A = 0.1

And b = 3 / A = 3/0.1 = 30

And the function is f(x) = 0.1* 30^x

KATRIN_1 [288]

Answer:

16 yards 2 feet

Step-by-step explanation:

You have 50 feet.  I subtracted 2 from this number so that it could be divisible by 3.  

One yard has three feet.

50 - 2 = 48

48 / 3 = 16
