Answer:
1) The Mass of Nitrogen in 
is<u> 14.00 gm.</u>
2) The Mass of Hydrogen in is<u> 3.00 gm.</u>
3<u>)</u>The Molar Mass of is <u>17.00 gm.</u>
Step-by-step explanation:
Solving for Part 1.
In that is Ammonia there is 1 atom of Nitrogen.
So the atomic mass of Nitrogen is same as the mass of Nitrogen in .
Atomic mass of Nitrogen = 14.00 gm
Hence The Mass of Nitrogen in is<u> 14.00 gm.</u>
<u />
Solving for Part 2.
In there are 3 atoms of Hydrogen.
Atomic mass of Hydrogen = 1.00 gm
So the mass of Hydrogen in is 3 times of its atomic mass.
Mass of Hydrogen = 3 × Atomic mass of Hydrogen
Hence The Mass of Hydrogen in is<u> 3.00 gm.</u>
<u />
Solving for Part 3.
In 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 .
Molar mass of =Mass of Nitrogen+Mass of Hydrogen
Hence The Molar Mass of is <u>17.00 gm.</u>
54.75 square feet is the answer
Answer:
130
Step-by-step explanation:
If you add fifty to eighty then you get 130, to double check just subtract 50 from 130 and then you get 80.

Answer:
<h2>Volume = 153938.0 cm³</h2>
Step-by-step explanation:
Volume of a cylinder = πr²h
where
r is the radius
h is the height
From the question
h = 10 cm
diameter = 140cm
We can find the radius using the formula
radius = 70 cm
Substitute the values into the above formula and solve
That's
V = (70)²(10)π
= 4900(10)π
= 49000π
= 153938.0400
We have the final answer as
<h3>Volume = 153938.0 cm³</h3>
Hope this helps you
