7. A 35.0 ml solution of 0.450 M CH;COOH is titrated with 0.300 M NaOH. The acid dissociation value for CH,COOH is 1.8 x 10%. a. Write out the dissociation equation for CH;COOH, complete the ICE box and determine the pH of the CH;COOH solution before any NaOH has been added. b. Determine the number of moles of CH;COOH present in the 35.0 ml of 0.450 M CH;COOH solution. c. What volume, in milliliters, of 0.300 M NaOH solution will be needed to neutralize the CH.COOH colu

What is the volume measurement indictatede in the volumetric glassware ? 1. Graduated Cylinder (PINK) 2. Delivery Pipette

A volumetric buret should always be read to _______ decimal places.

Tonya sold 160 sandwiches for $2.00 each. Each sandwich consisted of 4 oz of ham, two slices of bread, and mustard. She paid $3.00/lb for the ham, $0.60/loaf for the bread and used 8 jars of mustard at $0.50 each. How much profit did she make? Note: I attempted the problem, but it felt like I was going about it wrong. It’s for a chem class, but is there a less conveluded algebraic way to solve it? Or other method?

If I add 15mL of water to 8 grams of sugar in a volumetric flask, then swirl it to dissolve the sugar. Then add more water up to the 25 mL line, what is my total volume. I have the weight of the flask before and after as well.

5. Based on the tolerance table for volumetric glassware, the volume of a 25 mL volumetric pipet and volumetric flask is understood to be 25.03 mL 24.97 mL 25.00 mL 25 mL

When using the Dumas Method....   The student filled their 400 mL beaker with 250 mL of tap water and added 2 boiling stones.  They then sat their beaker on the hot plate and clamped it in place using a metal ring attached to a ring stand. The student began heating the beaker. The student obtained a 250 mL Erlenmeyer flask from the drying rack.  It looked clean but had a few water droplets inside.   The student cut out a 3 inch by 3 inch piece of aluminum foil and found a rubber band. The student determine the mass of the Erlenmeyer flask + piece of foil + rubberband.  The mass was 68.780 g. The student used a 10 mL graduated cylinder to measure out 4.5 mL of unknown liquid.  They added their unknown liquid to the 250 mL Erlenmeyer flask.   The student covered the Erlenmeyer with aluminum foil and rubber band.   Using a paper clip, the student poked 3 holes in the top of their aluminum foil The student then clamped their flask in the water bath, that hadn't started boiling yet.   When…

When we say that a Class A 25.00 mL pipet has a tolerance of 0.030 mL, what does that mean?
