How much 3M NaOH (MW=40) can be made from 10.0mL of a 10M solution?
vaieri [72.5K]

Explanation:

The given data is as follows.

              M_{1} = 3 M,           V_{1} = ?

              M_{2} = 10 M,         V_{2} = 10.0 ml

Therefore, calculate the volume of given solution as follows.

              M_{1} \times V_{1} = M_{2} \times V_{2}

Now, putting the given values into the above formula as follows.

            M_{1} \times V_{1} = M_{2} \times V_{2}

            3 M \times V_{1} = 10 M \times 10.0 ml    

                   V_{1} = 33.3 ml

or,                             = 0.033 L        (as 1 ml = 0.001 L)

Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.

           Molarity = \frac{\text{mass of solute}}{\text{molar mass of solute}} \times \frac{1}{\text{volume in L}}

               3 M = \frac{mass}{40 g/mol \times 0.033 L}

              mass = 3.96 g

Therefore, we can conclude that mass of NaOH is 3.96 g.

3. In one population, 18 individuals have long hair and 182 individuals have short hair. It is known thatmating has been random
pishuonlain [190]

Answer: p (short hair) = 0.91 and q (long hair) = 0.09

Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.

For this question, short hair is allele L and long hair is allele l

So, the frequency of short hair is p and of long hair is q.

To calculate the frequencies:

Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)

p = 182/200 = 0.91

The same formula goes for the recessive allele, so:

q = 18/200 = 0.09

Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
