You are given a protein solution with a concentration of 0.15 mg/ml.

Explanation:

The given data is as follows.

         Initial concentration = 0.15 mg/ml,        

        Final concentration = 0.1 mg/ml, (as \frac{0.1 microgram}{1 microliter} \times \frac{10^{-3}}{1 microgram} \times \frac{1 microliter}{10^{-3}ml})

        Final volume = 100 microliter \times \frac{10^{-3} ml}{1 microliter} = 0.1 ml

According to the dilution formula we get the following.

              C_{i} \times V_{i} = C_{f} \times V_{f}

or,                        V_{i} = \frac{C_{f} \times V_{f}}{C_{i}}

Putting the given values into the above formula we get the following.

                   V_{i} = \frac{C_{f} \times V_{f}}{C_{i}}

                               = \frac{0.1 mg/ml \times 0.1 ml}{0.15 mg/ml}

                               = 0.0667 ml

                               = 6.67 \times 10^{-2} ml \times \frac{1 microliter}{10^{-3} ml}                                

                              = 66.7 microliter

This means that volume of protein stock which is required is 66.7 ml. Hence, calculate the volume of water required as follows.

                  Volume of water required = Total volume - volume of protein stock

                                                     = (100 - 66.7)  microliter

                                                     = 33.3 microliter

Thus, we can conclude that we need 33.3 microliter of water and 66.7 microliter of protein.

Rashid [163]

Answer:

C.Melt both cubes and look for a broader range of melting temperatures. The one that melts over a broader range of temperatures is the amorphous solid.

Explanation:

Amorphous solids is one that do not have a fixed melting points but melt over a wide range of temperature due to the irregular shape hence its name. Contrariwise crystalline solids, have a fixed and sharp melting point.

This comes in handy to solve the riddle. We can characterise the pair with the melting point property.

Give all possible ml values for orbitals that have each of the following:<br> (a) l = 3;
Angelina_Jolie [31]

At l = 3, ml =+3,+2,+1,0,-1,-2,-3

What are quantum numbers?

  • Quantum numbers are used to describe where around a nucleus a particular electron can be found.
  • In any given atom, each electron can be described by four quantum numbers.
  • These are n,l,m1,ms
  • The values that each number can be are based on a set of rules.

What is a magnetic quantum number ?

  • It describes the orientation of the orbitals.
  • It is represented as ml.
  • The value of this quantum number ranges from (-l to +l).
  • When l = 2, the value of  will be -2, -1, 0, +1, +2.
