If the fluid inside a tree is about 0.3 M more concentrated in solute than the groundwater that bathes the roots, how high will a column of fluid rise in the tree at 24°C? Assume that the density of the fluid is 1.0 g/cm3. (The density of mercury is 13.6 g/cm3.)
How much water would I need to add to 500mL of 2.4 M KCl solution to make a 1.0 M solution?
the initial pH value was2.5. You found that pH=pKa=4.2 when 12.50 mL of NaOH hadbeen added. The concentration of the sodium hydroxide was 0.500M. Calculate the molar mass of the acid
