How many moles of kcl are in 28 g of kcl
WebVanadium pentoxide does not have good water solubility; therefore, it was dissolved in an alkaline 0.25 mol/L potassium carbonate solution. Only 2.5 g vanadium pentoxide was able to be dissolved in a 100 ml solution. Nevertheless, the spongolite was soaked in the 2.5% vanadium pentoxide solution for two hours and subsequently calcined at 675° C. WebA 25.0-mL sample of vinegar (which contains the weak acid acetic acid, CH3CO2H) requires 28.33 mL of a 0.953 M solution of NaOH for titration to the equivalence point. What is the mass of acetic acid (molar mass = 60.05 g/mol), in grams, in the vinegar sample, and what is the concentration of acetic acid in the vinegar?
