A volume of 60.0 mL of aqueous potassium hydroxide(KOH)was titrated against a standard solution of sulfuric acid(H2SO4). What was the molarity of the KOH solution if 24.7 mL of 1.50M H2SO4 was needed? The equation is: 2KOH(aq)+H2SO4(aq)-->K2SO4(aq..
If the sample contains a combined total of 1.75 grams per mole and has a total mass of 51.0 grams, what are the percentages of CO2 and Ne in the sample by mole?
Suppose a mixture of oxygen and nitrogen is prepared in which there are 0.200 mol oxygen and 0.500 mol nitrogen. a) What are the mole fractions of the gases. b) If the total pressure of the mixture is 745 torr, what are the partial pressures of th..
PVA (polyvinyl alcohol) strands can form hydrogen bonds between different parts of the same strand. Illustrate how this can occur by using a sketch to show the hydrogen bonding.
