Answer:
8.33mol/L
Explanation:
First, let us calculate the molar mass of of formaldehyde (CH2O). This is illustrated below:
Molar Mass of CH2O = 12 + (2x1) + 16 = 12 + 2 + 16 = 30g/mol
Mass of CH2O from the question = 0.25g
Number of mole CH2O =?
Number of mole = Mass /Molar Mass
Number of mole of CH2O = 0.25/30 = 8.33x10^-3mole
Now we can calculate the molarity of formaldehyde (CH2O) as follow:
Number of mole of CH2O = 8.33x10^-3mole
Volume = 1mL
Converting 1mL to L, we have:
1000mL = 1L
Therefore 1mL = 1/1000 = 1x10^-3L
Molarity =?
Molarity = mole /Volume
Molarity = 8.33x10^-3mole/1x10^-3L
Molarity = 8.33mol/L
Therefore, the molarity of formaldehyde (CH2O) is 8.33mol/L
C. Condensing.
Why: Because, Condensing means to make something denser or more concentrated.
Hope this helps! ;)
It's 77C.......................
Explanation:
Hydrochloric acid does not consider as organic acid because of the absence of carbon in it.
hope it helps
Hello there!
Formulas have helped us understand the compound structure and its behavior by letting us know the exact composition of a molecule.
Different atoms have different properties, also, a different arrangement of atoms lead to different geometrical shapes. To understand compound structure and behavior it is necessary to know which atoms are in the molecule and how are they arranged. These two pieces of information can be obtained from the Chemical Formula, which tells us precisely the atoms and the proportions of each one in a given compound.
Have a nice day!
