Question I need help understanding how to do volume calculations and Molarity of NaOH? Our professor is useless and does not throughly explainData: Trial 1: Initial Vol NaOH: (20.5 mL, pH=3.8) Final Vol: (25 mL, pH=8.3) Trial 2: Initial Vol NaOH: (13.3 mL, pH=1.65) Final Vol: (22 mL, pH=7.36) Trial 3: Initial Vol NaOH: (4 mL, pH=2.65) Final Vol: (12 mL, pH=7.06) Trial 4: Initial Vol NaOH: (22.5 mL, pH=3.05) Final Vol: (39.2 mL, pH=7.9)Q1) average volume of NaOHQ2) how do i find Moles of baseQ3) Molar ratio ?Q3) how do i find the molarity of NaOH?

If the moles and volume of a gas are held

A. Plot the volume (mL) of the air sample vs.

Question A. Plot the volume (mL) of the air sample vs. its pressure (atm) and determine the equation of the line. Record your results below. Include the graph in your report. (If you have a straight line you can use the equation for a straight line (y = mx b). If the line is a curved line you can test to see if the plot is a power function (y = x2) or a logarithmic function (y = log x). This can be made easier if you are using a graphing or data analysis program like ExcelTM. Your instructor can show you how to do this.)  B. Write an algebraic equation showing the relationship between volume and pressure of the air sample. This relationship is known as Boyle’s Law. If the volume of the sample of air you are studying was expanded to 50 mL, what would its pressure be? Volume- 40 38.237.837.437.236.835.835.2pressure atm- 0.8750.9170.9260.9410.9510.9670.9780.995

During a “Synthesis of Alum” experiment, a student uses 0.500g

Question During a “Synthesis of Alum” experiment, a student uses 0.500g of aluminum foil and dissolves it with 24.9 mL of 1.4M KOH. After cooling the mixture, the student adds 11.9mL of 9.0M H2SO4. Given the following balanced equation: 2AL(s) 2KOH(aq) 4H2SO4(aq) 22H2O(I)—> 3H2(g) 2 KAl(SO4)2 x 12H2Oa.) calculate the theoretical yield of alum. Show the process of finding the limiting reactant. [Molar mass (alum) = 474.3g/mol Alum]b.) If the student isolates 6.502g of alum as crude product calculate the percent yield.
