Ihave no idea how to do this
uranium has an atomic weight of 238 amu.
weight of one mole of uranium = /mol
weight of one mole of oxygen = 16.00 g
the molar mass or molecular weight for u205 is /mol.

Determine the percent sulfuric acid by mass of a 1.61 m aqueous solution of h2so4. %

One of the few xenon compounds that form is cesium xenon heptafluoride (csxef7). how many moles of csxef7 can be produced from the reaction of 13.0 mol cesium fluoride with 12.5 mol xenon hexafluoride? csf(s) + xef6(s) csxef7(s)

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
