Calculate the limit of resolution for the oil lens of your microscope Assume an average wavelength of 500nm
What volume of 0.300 N NaOH would be required to bring 16.0 mL of distilled water that has a pH 7.00 to a new pH of 12.42?
How much water must be added to 534. mL of 0.180 M HCl to produce a 0.135 M solution? (Assume that the volumes are additive.)
Suppose you were given a pure stereoisomer that rotated the plane polarized light either +60 degrees or -120 degrees, i.e a uniform colour is observed for both of these readings.
Calcium fluoride, CaF2, is a source of fluorine and is used to fluoridate drinking water. Calculate its molar mass to four significant figures.
