Given you have 1.93 mols of NaCl, find the molarity of a 2.5 L solution

Inessa [10]

Answer:

0.77 M

Explanation:

Molarity is the concentration of a solution per liter

C= concentration

n= number of moles

V= volume of solution

The formula we will use is C= n/V

C= n/V

C= (1.93 mol NaCl)/(2.5 L of solution)

C= 0.772 mol/L

Since this concentration is given in moles per liters of a solution, this concentration is also the molarity.

C= 0.772 mol/L

*Include two significant digits in final answer*

M= 0.77 M

Draw the lewis structure(s) for the molecule with the chemical formula c2h3n,c2h3n, where the n is connected to only one other a

lara [203]

The possible structure for given Chemical formula is given below, It is asked that the Nitrogen atom is connected to only one atom. As, nitrogen is involved in making three bonds so it is only possible for Nitrogen to make three bonds with Carbon atom having the capacity of forming four bonds. The possible structure is Acetonitrile. In which N is connected to Carbon atom through triple bond as shown below,

Result:
In current structure in which N is attached to only one atom, there is no double bond. So, the answer is ZERO.
