1. Calculate the moles of 3-methyl-1-butanol and acetic acid from the starting volumes. Given that we are adding 5.0 mL of 3-methyl-1-butanol, 7.0 mL of glacial acetic acid all intoto a 50 mL round bottom flask. 1a. If we are reacting 3-methyl- 1-butanol (AKA isopentyl alcohol or isoamyl alcohol) with an excess of anhydrous acetic acid( acetic acid )to form isopentyl acetate also calculate the theoretical yield of isopentyl acetate in grams

A student prepares a 0.29 M aqueous solution of propionic acid (C₂H,CO₂H). Calculate the fraction of propionic acid that is in the dissociated form in his solution. Express your answer as a percentage. You will probably find some useful data in the ALEKS Data resource. Round your answer to 2 significant digits. % X

make 100.0 mL of either 1.0 M or 0.10 M ethanol (aqueous). Start with a stock ethanol solution that is 95.0% ethanol by mass and has a density of 0.789 g/mL.

Wine goes bad soon after opening because the ethanol (CH3CH₂OH) in it reacts with oxygen gas (0₂) from the air to form water (H₂O) and acetic acid (CH₂COOH), the main ingredient of vinegar. What mass of water is produced by the reaction of 8.9 g of ethanol? Round your answer to 2 significant digits. 08 g x10 ? Ⓒ2022 McGraw Hill LLC. All Rights Reserved.

Procedure A: Molarity (M=g/MM/L) Step 1. Place one-eighth of a teaspoon (this weighs approximately 0.5 grams) of NaCl (table salt) in the graduated cylinder provided. Then add distilled water to that graduated cylinder until the level of the water reaches 45.00 mL. Mix thoroughly about 1 minute. Pour solution into a somewhat clear cup. Remember what this looks like for Procedure B. Questions: Is this a saturated solution? Why or why not? Take a picture and insert a picture (compress your image) of your solution here. Save this solution for Step 2. Calculations: Determine the Molarity of this solution using the formula M = g/MM/L. You know the grams (one-eighth of a teaspoon weighs approximately 0.5 grams), look up the Molar Mass of NaCl, and convert your mL to L to solve the problem.) Show your calculations for Molarity here.

3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solutioni is water. In a hardware store, you can buy industrial strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume of vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the'first minute of each reaction, and he records the data below. Volcano # 1 Volume of gas produced (m) vs Time (s) for Volcano t Time (s) Volume of gas produced (mL) 10 25 38 40 20 30 46 30 Volume of gas produced (ml) 50 40 50 52 60 53 40 Time ( 20 60 Volcano 2 Volume of gas produced iml) vs. Time is) for Vocano 2 Volume of…
