Lab 1: Density Block Write Up

Lab 1: Density Block Write Up


Introduction:

In this density block lab, we were trying to determine the mass of a block using its density and volume using a ruler.

Purpose: 

The purpose of performing this experiment is to use a ruler to measure the length, width, and height in centimeters to determine the volume and then multiplying the density of the block to determine the mass. With the result we turn it into a significant figure and measure the actual mass against the one we calculated. if it is more than 5% off, we needed to redo the procedure. 

Data:

After 3 tries:

Calculated Mass:
L (2.50) * W (2.48) * H (2.50) * D (7.5) = 116.25 -> SF= 120

Actual Mass: 
123.6 

Percent Error: 
2.9%

Discussion/Conclusion:

We fulfilled the purpose of the lab in the way that we found the mass of the block with a 2.9% error after calculating the mass with the ruler. The possible errors that could have occurred in this lab was measuring the length, width, and height of the block with the small measurements that could easily off by a few numbers. What I learned from the lab was the different ways to calculate mass and how there can be mistakes along the way where you need to make sure of your measurements are correct. For future lab investigations, I would want to have more time to have multiple trials to get the smallest amount of percent error possible.

Lab 4: Atomic Mass of Candium

Atomic Mass of Candium Purpose: The purpose of this lab was to find the average atomic mass of the element candium. To test this we used three candium isotopes being, M&M's, Pretzel M&M's and Skittles. Average Atomic Mass: .77 amus Conclusions: 1. Ask a group nearby what their average atomic mass was. Why would your average atomic mass be different than theirs? Another groups average atomic mass was 1.0 amus. Our average would be different than others because the variations of the isotopes and weight was different for each group. 2. If larger samples of candium were used, for example if I gave you a whole backpack filled with candium, would the differences between your average atomic mass and others' average atomic masses be bigger or smaller? Defend your answer. The average atomic masses would be smaller because there would be more amounts of candium meaning a larger amount to divide among and the weight of the outliers would round out. 3. If you took any

Lab 21: Titration Lab

Lab 21: Titration Lab Set Up of the Lab  Analayte at equivalence (pale pink) Summary of Procedure: The first step to this lab was rinsing the burette with water and then with the base NaOH. After rinsing, we filled the burette with 0.25 NaOH up to the 0mL line using a funnel. For the first trial, we measured out 7.08 mL of vinegar which was our acid and 20 mL of water. We added it to our erelymer flask and 5 drops of the phenolphthalein acid. We put in our magnetic stirrer and put the flask on top of our hot plate and turned on the spinner to 160 RMPs which started the automatic mixing. We added the NaOH in slow increments. For the first try, we went a few drops over using 23.20 mL of the base. We did repeated the steps but with 7.02 mL of the vinegar (acid) and used 24.21 mL of the base and we slowly dropped in the NaOh until it reached a faint pink color when the analayte reached equivalence.  Data: Percent Ionization: [H3O+] / [CH3COOH] x 100 = 0.50%

Lab 14: Create a Smell Lab: Ester Synthesis

Lab 14: Create a Smell Lab: Ester Synthesis During this lab, we learned how a molecule can be changed into a different molecule using chemistry. We created different smells with acids like salicylic acid, acetic acid and sulfuric acid. Along with the acid's there were also alcohols that we used including isopentyl alcohol and methyl alcohol. We transformed the smells into esters by mixing certain alcohols with acids to create an initial smell and when put into the hot water it changed into an ester. 1. The odors of the first mixture before heating was a sharp, sour candy with a medicinal smell and after heating it was a sweeter smell of banana laffy taffy's with a hint of a nail polish smell. The odors of the second mixture before heating was a smelly vinegar and after heating it was an intense nail remover smell. The odors of the third mixture was a sweet/sour, sour patch kids candy smell and after heating it smelled like minty, wint o green lifesavers. They are differ
