How do you find the mass of an unknown acid in a 10mL portion used for titration if my original mass of the unknown acid is 0.307g and was in a 100mL volumetric flask
Calculate what the pH is at 0 mL added strong acid, the quarter-, half-, and three-quarter-equivalence points, the equivalence point, and when excess acid has been added.
If the density of the solution is 1.1094 g/mL, what is the molarity of the sulfuric acid?
How much heat was transferred from the tank? b) What is the final temperature of the tank contents? c) How much steam condensed, in kg? for a i found the difference in enthalpies but i cant figure out b, c
suppose new element with atomic number 120 is discovered.if some isotopes of this element have 122 nuetrons and some have 124 neutrons,what can you infer about the atomic mass of the element.
