Titration is a common method of determining the amount or concentration of an unknown substance. The method is easy to use if the quantitative relationship between two reacting solutions is known. The method is particularly well-suited to acid-base and oxidation-reduction reactions. Titrations are routinely used in industry to analyze products to be sold. Many manufacturers are under strict standards of quality control because their products are sold for public consumption. In this experiment, we will analyze a number of commercial products and, in some cases, test the validity of the information given on their labels and/or the claims made in television commercials. The products to be tested include antacid tablets, vinegar, fruit juice, and household ammonia.
Just want to help you understand :)) If you need any more help comment on this and I will be glad to help :D
Answer:
Explanation:
D. Parasitism
The mosquito is taking blood from the human, and injecting malaria and other irritations
N2 + 3H2 ------> 2NH3
According to the equation;
3 mol of hydrogen will produce 2mol of ammonia.
1 mol of hydrogen _____________________?
= 2 × 1/3
= 0.67 mol
Total volume of the solution formed will be 32.5 liters
Given:
Molarity of solution = 0.0200 m
mass of nacl = 38.0 grams
To Find:
total volume of the solution
Solution: Molarity is defined as the amount of solute present in 1 L of solution. The equation used to determine molarity of the solution follows:
M = given mass of nacl/molar mass of nacl*1/volume of solution
volume of solution = given mass/molar mass*1/molarity
volume = 38/58.5*1/0.02 = 32.5
Hence, volume of solution = 32.5 litres

Okay, to do this you have to work with the relative molecular mass (RMM). You can get this from looking at the periodic table.
The RMM for the whole molecule is:
58.933 + (2 x 35.453) + (12 x 1.008) + (6 x 15.9994) = 237.96
Then you work out the RMM for water:
(2 x 1.008) + 15.9994 = 18.0154
As there are 6 moles of water in this molecule then multiply the RMM of H2O by 6 = 108.0924
Finally, divide the total H2O RMM by the total molecule RMM and multiply by 100 to get a percentage:
(108.0925 / 237.96) x 100 = 45.42%
