One of the hydrates of \( \mathrm{CoSO}_{4} \) is cobalt(II) sulfate heptahydrate. A 63.3 gram sample of \( \mathrm{CoSO}_{4} \cdot 7 \mathrm{H}_{2} \mathrm{O} \) was heated thoroughly in a porcelain crucible, until its weight remained constant. After heating, how many grams of the anhydrous compound remained?
For the following reaction, \( 4.71 \) grams of water are mixed with excess diphosphorus pentoxide. The reaction yields 12.4 grams of phosphoric acid . diphosphorus pentoxide (s) + water ( 1\( ) \longrightarrow \) phosphoric acid (aq ) What is the theoretical yield of phosphoric acid? grams What is the percent yield for this reaction?
