Answer: The molarity is 0.25 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.
where,
n = moles of solute
= volume of solution in ml
moles of =
Now put all the given values in the formula of molality, we get
Therefore, the molarity is 0.25 M
Answer:
bond angle = 120 °
Explanation:
Lewis structure is used to represent the arrangement of the electrons around the atom in a molecule. The electrons are shown by dots and the bonding electrons are shown by line between the two atoms.
For ,
The number of valence electrons = = 6
The skeleton structure of the compound is in which one C molecule act as a central atom and is bonded to the three H with one sigma bond each.
Number of valence electrons used in skeletal structure = 6
So,
Remaining valence electrons = 0
The Lewis structure of the compound is shown below:
H
:
C⁺
: :
H H
<u>The geometry is trigonal planar which has an angle of 120 °.</u>
