What observed rotation is expected when 1.26M solution of (R)-2-butanol is mixed with an equal volume of a 0.630 M solution of racemic 2-butanol, and the resulting solution is analyzed in a sampling container that is 1 dm long? The specific rotation of (R)-2-butanolis -13.9 degrees mL g^(-1) dm^(-1).
A 2.067-g sample of a monoprotic acid was dissolved in water. It took 25.24 mL of a 0.1578 M NaOH solution to neutralize the acid. Calculate the molar mass of the acid.
If the molality of your solution is 0.30, calculate the contribution to the percentage error in your results due to not correct for the errors in the thermometer readings.
What would the molecular diagram look for oxygen bonding with bromine. Which are the bonding and which are the antibonding. When we did it this in class there were 8bonding and 5 anti. using a template.
the energy required to melt 1.00 g of ice at 0 degrees celcius is 333 j. if one ice cube has a mass of 62.0 g and a

What is the pH of a 1.3 * 10^-7 M solution of benzoic acid at 25C. pKa of benzoic acid is 4.19 at 25C. (Might have to take into account the autoionization of water).
The method of standard additions was used to determine nitrite in a soil ample. an aliquot of 1.00 mL of the sample was mixed with 24.00 mL of a colorimetric reagent, and the nitrite was converted to a colored product with an absorbance of 0.300.
A 475 mL sample of gas is collected over water at 27°C and a total pressure of 675 mm Hg. If the vapor pressure of water at 27°C is 26.7 torr, what is the volume of the gas sample at standard pressure?
