Serial dilution problem: Six test tubes are placed in a rack. To each tube add 4 mL of saline solution. Now to the first tube ad

d 0.5 mL of concentrated protein (10 M) and mix well. Then transfer 1 mL of tube # 1 to tube # 2 and mix well. 1 mL of the contents of tube # 2 is then transferred to tube # 3, and the procedure is repeated for the remaining tubes. What is the dilution factor and molar concentration of protein in tube # 4? Show your answer by drawing 6 tubes and label them.

Answer:

The dilution factor of protein in tube # 4 is 125. Molar concentration is 0.0088 M protein

Explanation:

The dilution factor indicates how many times is more concentrated a main solution in relationship with a diluted solution. In this case, the main solution is in tube #1. For calculating the dilution factor and molar concentration in tube #4 we need the main solution concentration which comes from next equation:

Initial volume * initial concentration = final volume * final concentration

0.5 mL * 10M = 5mL * final concentration

1.1 M = final concentration = main solution concentration

Applying the same equation for remain tubes we have 0.22 M for tube #2, 0.044 M for tube # 4 and 0.0088 for tube # 4.

Dilution factor = Main solution concentration/tube 4 concentration

Dilution factor = 1.1/0.0088 = 125

I hope my answer helps you

Write the balanced chemical equation for the Haber-Bosch process, that is, the combination of nitrogen and hydrogen to form ammo
RoseWind [281]
The balanced chemical equation for the Haber-Bosch process is N₂(g) + 3H₂(g) → 2NH₃(g). The Haber-Bosch process played a significant role in boosting agriculture back in the day. It paved the way for the industrial production of ammonia which is used in the manufacture of fertilizers. The process involves reacting atmospheric N₂ with H₂ using a metal catalyst under high temperature and pressure.

How does the properties of matter in liquid and gas state allow the Herons fountain to work?
Varvara68 [4.7K]

Answer:

Heron's fountain is an hydraulic machine that works because or the pressure inside of the system. Water will flow from high gravitational potential energy to low gravitational potential energy. The two sides of the system will present different pressure because they have different fluids in it (water and air) and  water pressure is higher than gas/air pressure, so it will flow.

It is important to take into account that the pressure in the columns is a function of the height of the fluid (water or air).

Explanation:

<u>The properties of liquid:</u>

- If a liquid is poured into a container, it will adapt to the container's shape

- In a liquid state, the molecules have a kinetic energy higher than in a solid state

- Liquid particles are not arranged in a regular way but they are very close  to each other, that's why liquids have a definite volume.

- Force is spread in an even way through a liquid, so the liquid particles are displaced if an object is placed in it.

- Liquids, as solids, can't be compressed

<u>The properies of gas:</u>

- They are everywhere

- Gas molecules are disorganized and have a great deal of space between them

- Gas fill up any container and spread indefinitely

- Gas molecules have a high kinetic energy

- If gas is put under pressure, the space between particles will decrease and collisions between them will increase.

- If the temperature of the gas increases in a container, the pressure will increase; if the temperature decreases, the pressure sill decrease.

- It can be compressed

- Gas has no definite volume nor definite shape.
