g You titrate an unknown sample of oxalic acid (H2C2O4 (aq)) to determine its concentration. After noting the volume of the oxalic sample is 112.6 mL, you add a few drops of phenolphthalein indicator and titrate to the endpoint using 45.2 mL of a standardized 1.5 M NaOH solution. Find the molarity of the oxalic acid sample.

Nitrogen (n), phosphorus (p), and potassium (k) are the main nutrients in plant fertilizers. according to an industry convention, the numbers on the label refer to the mass percents of n, p2o5, and k2o, in that order. calculate the n: p: k ratio of a 30: 10: 10 fertilizer in terms of moles of each element, and express it as x: y: 1.0.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
