Answer:
1.2,dibromoethane is the sha'awa .
Answer:
Explanation:
Answer:
A. to determine the efficiency of the reaction
Explanation:
Percentage is the ratio of the actual yield to theoretical yield as a percentage. It is calculated by dividing the actual yield by theoretical yield then multiplying by 100%.
Calculation of percentage yield is important as it helps in the determination of efficiency of a reaction. For example in most industries for the purpose of making the most product with the least waste.
Additionally, calculating the percentage yield helps in determining other products that may be formed during the reactions.
3.3256 Liters
See the image I have shared to you above
Given that the question gives us concentration (M) and volume, we can use these so get moles. remember that Molarity (M)= mol/ Liters, so if we want the moles, then
moles= M x L
moles= 1.13 x 5.60= 6.33 moles KI
now to get the mass in grams, we need the molar mass of potassium iodide (KI) which can be determined using the periodic table and add the masses of each atom.
molar mass KI= 39.1 + 127= 166.1 g/mol
6.33 mol (166 g/ 1 mol)= 1050 grams KI
