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.

How does using killed or weakened bacteria in an immunization help the body prevent infections
snow_lady [41]
<span>Basically, the body needs to know what it is defending against. Your body can still (usually) fight off infection, even without an immunization, but it takes longer. Basically, your body creates cells with a receptor for a specific disease. When this cell finds the disease it is programmed for, it will send out signals to the "killer" cells to come and kill it. If your body doesn't have the "seeker" cells, it can't fight off the infection until it does. The opposite end are autoimmune diseases, where your immune system starts attacking itself.
