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 14.00 gm.

2) The Mass of Hydrogen in $NH_3$ is 3.00 gm.

3)The Molar Mass of $NH_3$ is 17.00 gm.

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 14.00 gm.

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 3.00 gm.

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 17.00 gm.

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
