what is the number of molecules of c2h6o required to have 135 atoms in total?
each molecule has 2 + 6 +1 = 9 atoms
135/9 = ?
the answer is 11.1 but i dont know how to get it
If you have C2H6O that is 9 atoms/molecule
135/9 = 15
That is ethanol
C2H6O4 would be 12 atoms / molecule
that would give you 135/12 = 11.25
That is dioxydimethanol
I have a hunch you have a typo somewhere
135/what = 11.1
what = 12.162 atoms/molecule. That makes no sense.
To find out the number of molecules of C2H6O required to have 135 atoms in total, we need to break down the compound C2H6O and determine the number of atoms it contains.
C2H6O represents ethanol, which consists of 2 carbon atoms (C), 6 hydrogen atoms (H), and 1 oxygen atom (O).
To calculate the number of atoms, we add up the number of atoms of each element in the compound.
Total number of atoms in C2H6O = (2 carbon atoms) + (6 hydrogen atoms) + (1 oxygen atom)
= 9 atoms
So, C2H6O contains a total of 9 atoms.
Now, to determine the number of molecules of C2H6O required to have 135 atoms, we can set up a simple proportion:
Number of molecules of C2H6O / Total number of atoms in C2H6O = Given total number of atoms / Number of atoms in one molecule of C2H6O
Number of molecules of C2H6O / 9 = 135 / 1
To find the number of molecules of C2H6O, we can multiply both sides of the equation by 9:
Number of molecules of C2H6O = (135 / 1) * 9
Therefore, the number of molecules of C2H6O required to have 135 atoms in total is 1,215 molecules.
