Answer:
The experiment report is a detailed discussion of the methodology followed in the experiment.How to write summary of experiment resultsAfter carrying out a laboratory experiment it is often expedient to write a summary of the experiment usually for the purpose of assessment by the instructor.Such reports begin with the title of the experiment followed by the material used in the experiment. Next comes the procedure of the experiment where all the details of the experiment are spelt out in detail.Lastly, you can now write the conclusion and the results obtained from the experiment in the last paragraph of the report.
Explanation:
Answer:
Option B. 25mL
Explanation:
Step 1:
Data obtained from the question:
Molarity of stock solution (M1) = 6M
Volume of stock solution needed (V1) =..?
Molarity of the diluted solution (M2) = 0.5M
Volume of diluted solution (V2) = 300mL
Step 2:
Determination of the volume of the stock solution needed.
Using the dilution formula, we can easily find the volume of the stock solution needed as follow:
M1V1 = M2V2
6 x V1 = 0.5 x 300
Divide both side by 6
V1 = (0.5 x 300) /6
V1 = 25mL
Therefore, 25mL of 6M NaOH is needed.
Answer: 1.27 bar
Explanation:
1 atm = 1.01325 bar
1.25 atm = Z (let Z be the unknown value)
To get the value of Z, cross multiply
Z x 1 atm = 1.25 atm x 1.01325 bar
1 atm•Z = 1.2665625 atm•bar
To get the value of Z, divide both sides by 1 atm
1 atm•Z/1 atm = 1.2665625 atm•bar/1atm
Z = 1.2665625 bar
(Round up Z to the nearest hundredth as 1.27 bar)
Thus, 1.25 atm when coverted gives 1.27 bar
The atomic number of an atom is determined by the number of protons it has..
It is also the whole number shown on the periodic table
