What are the molarity and the normality of a solution made
Nikitich [7]

Explanation:

It is known that molarity is the number of moles present in a liter of solution.

Mathematically,    Molarity = \frac{\text{no. of moles}}{\text{volume in liter}}

Hence, calculate the molarity of given solution as follows.

     Molarity of citric acid = \frac{\text{mass of citric acid}}{\text{molar mass of citric acid}} \times \frac{1}{\text{volume of solution(L)}}

                                 = \frac{25 g}{192.13 g/mol} \times \frac{1}{0.75 L}

                                 = 0.173 M

As citric acid is a triprotic acid so, upon dissociation it gives three hydrogen ions.

          Normality = Molarity × no. of hydrogen or hydroxide ions

                            = 0.173 × 3

                            = 0.519 N

Thus, we can conclude that molarity of given solution is 0.173 and its normality is 0.519 N.

When might a dominant trait appear?
daser333 [38]

Answer:

A dominant allele will always allow a specific trait to show up no matter if we have two dominant copies (BB) or just one (Bb). A trait from a recessive allele will only appear if it is paired with another recessive allele

Zielflug [23.3K]

Answer:

B

Explanation:

Molarity measures the strength of a solution. Remember, a solution is made up of two parts: the solvent (which does the dissolving) and the solute (the substance that is dissolved). The more solute there is, the higher the concentrate and therefore the higher the molarity of the solution. Thus B is the answer
