The number of hydrogen atoms are 304
<em><u>Solution:</u></em>
Given that a water molecule is made up of three atoms
Number of atoms in water molecule = 3 atoms
1/3 of the atoms are oxygen and the remaining Adams are hydrogen
There are 114 water molecules
8/3 of water molecule is hydrogen
<em><u>Therefore, number of hydrogen atoms is given as:</u></em>
Thus number of hydrogen atoms are 304
The answer is 5! Hope this helps!
Answer:
616 square centimeters
Step-by-step explanation:
Area of a circle is equal to pi × r^2. In this case, they have asked that you substitute 3.14 or 22/7 for pi, so I will be using 22/7, instead.
Diameter is equal to 2r; to find the radius, simply divide 28 by two. This gives us a radius of 14.
Multiply 14 squared by 22/7:
(22/7)(14^2)
This gives us (22/7)(196); (4312/7); 616.
Therefore, the area of the circle is approximately 616 square centimeters.
Answer:
f(7) = 22 or x =2
Step-by-step explanation:
- f(x) = 3x + 1
- f(7) = 3(7) + 1
- f(7) = 21 + 1
- f(7) = 22
<u>Or if the equation meant it like this:</u>
- f(x) = 3x + 1
- 7 = 3x + 1
- 6 = 3x
- 2 = x
