Question

Hello everyone! I thank you for your help but I'm having trouble with these problems as well. I appreciate you guys!

Based on the method that we learned in class to estimate specific gravities and the follo wing atomic weights, what H2C. (CH2)n o carboxylic acid has a density closest to that of water? C 12, H 1, O 16 e.. not a.-d. a. n 1 6. The correct answer of question 5 should be? a. totally miscible (soluble) in water totally miscible in water b. not c. cannot be estimated 7. Given the pKey of propan-1-ol is -0.25, starting with 0.5 g of propan-1-ol in 10 mL of octan-1-ol: to nearest tenth of a gram, how much propan-1-ol would be extracted into 30 mL of water? b. 0.3 d. 0.1 c. 0.2 e. not a.-d. a. 0.4 8. Given its pKais 10, to the nearest whole number what is the pH of a 1 M solution of phenol? d. 8 e. not a.-d. c. 6 9. Given the pKas above the acids and the molarity of reagents below, to the nearest hundreds how much in molarity of each product will be formed in the following reaction? 0.3 0.2 NO NO O N NO NO 1.0 M 1.0 M d. 0.64 a. 0.36 b. 0.47 e. not a.-d. c. 0.53

Explanation / Answer

specific gravity = density of the substance/density of water

If the specific gravity is very small density of the substance = density of water

In order to have a small specific gravity, molar mass has to be small.

answer is (a) n= 1
