Answer:
228 hydrogen atoms
Step-by-step explanation:
In a water molecule,
1/3rd is oxygen atoms, and
2/3rd (1 - 1/3 = 2/3) is hydrogen atoms
If there are 114 water molecules,
Total number of atoms would be:
3 * 114 = 342 (1 oxygen and 2 hydrogen atoms in 1 water molecule)
Out of these, 2/3rd would be hydrogen atoms, so:
There would be 228 hydrogen atoms
Find the Greatest Common Factor (GCF)
GCF = 2
Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
2(16x/2 + 42y/2)
Simplify each term in parenthesis
<u>C. 2(8x + 21y) </u>
Answer:
Since each ball has an equal chance of being drawn: 16 p = 1, or ... You can either apply the first equation to find that. B = 1 - R = 3/8 ...
