Why is it better to use 10.0mL or greater of a liquid in measuring its density?

how do you convert Joules to reciprocal cm (cm-1) ?

Part C - Type the number of significant figures that the result of the following aritmetic calculation should have. The answer must be a whole number. [(1.34x105) x ( 0.000311) 0.078] (110.8)

If the temperature for one of the runs in 52 degrees celcius, what is the 1/temperature(K)y value that will be plotted?

An instrument uses potassium bromide as one of the compounds in the analysis of noble gases of a planet.  Potassium bromide has a specific gravity of 2.38 and a molecular weight of 119 grams per mole [gmol]. Assume the spacecraft has a liquid sample of potassium bromide onboard that fills a 1.35-gallon [gal] container.  What is the amount of the potassium bromide sample in the container, in units of moles [mol]?

The mass of a beaker is 8.342 grams. After 3.00 ml. of an organic liquid is pipetted into the beaker. the combined mass of the beaker and the organic liquid is 10.697 grams. From the dat, what is the measured density of the organic liquid ?

(65.431 + 12.09) X 1.03solve using appropriate number of significant figures

2. At SATP, the theoretical K, value for ethanoic acid is 1.8 x 105 in pure water. A) Calculate percent error of the K, you determined to this standard value. % Error Theoretical Value - Experimental Value Theoretical Value X 100 B) Suppose that you used an indicator that fell in the buffer zone of the titration curve. Explain how the source of error either increased or decreased the Ka that was derived from experimental data. 3. Based on your results, calculate the pH of the solution at equivalence point. Comment on this pH (i.e. why is it neutral, acidic, or basic). Remember the K, = 1.8 x 105.

A sample of oxygen gas initially at 311 K311 K was heated to 365 K.365 K. If the volume of the oxygen gas sample at 365 K365 K is 937.9 mL,937.9 mL, what was its volume at 311 K?

A mixture of methane (CH,) and butane (C,H) at one atmosphere pressure and 25°C has a density of 1.583 g/L. Assuming ideal behavior, what is the mass in grams of carbon that are in 1 liter of the mixture?
