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
I will assume that line 4 bisect line x exactly in half. This means that if we solve the last side of the triangle like seen in the pic below we will know what half of line x is
To find the length of the last side of the triangle (let's call this y) you must use Pythagorean theorem
a and b are the legs (the sides that form a perpendicular/right angle)
c is the hypotenuse (the side opposite the right angle)
In this case...
a = 4
b = y
c = 6
^^^Plug these numbers/variables into the theorem
solve for y
16 + = 36
= 20
x = √20
x ≈ 4.472
^^^This is only half of x so if you double it then it will get you the full length of x
4.472 * 2 = 8.944
8.9 (D)
Hope this helped!
