Homework Answers
To calculate it, we use the formula weight of the starting material / molecular weight of the starting material ×molecular weight of the second reactant.
I.e. 0.221/210.23× 210.28 = 0.22105 in grams.
To.convert it into ML, divide this value by density, i.e., 0.22105/1.07 = 0.206 ml. This is the value.
Add Answer to:
diphenyl is 1.07 density and benzil is 1.23

Let's say, you did this part of the experiment and you found that for 0.06 grams of unknown acid, you needed 7.85 mL of 0.05M NaOH to reach the equivalence point. Question: How many grams of unknown acid you would need to titrate 25 mL of 0.05 M NaOH? Hint: Use the formula from the lab manual, page 94. (2 points)

what would be the percent yield if the final weight of my product
is 0.1357g this is a green chemistry wittig reaction to produce
1,4-diphenyl-1,3-butadiene from benzyltriphenylphosphonium chloride
and trans- cinnamaledyde using sodium hydroxide as the base
You will be using a Green Chemistry Wittig reaction (NOT Wittig-Horner Emmons reaction) to produce 1,4-diphenyl-1,3-butadiene starting with benzyltriphenylphosphonium chloride and trans- cinnamaledyde using sodium hydroxide as the base. This reaction is considered a "green" reaction, because an aqueous solution will be used...
