Solution A is 0.2400 M Ca(NO)2(aq). Solution A is diluted by a factor of 3 to form Solution B. AszOs(s) reacts with NO3"(aq) to produce NO(g) and HJASO4(aq) When As2O3(8) was added to 27.50 mL of Solution B, 1.710 x 1021 molecules of NO(g) were obtained from the reaction in 88.75% yield. (a) If As2O3(s) was the limiting reactant, calculate the mass of As2Os(8) which reacted with NOS (aq). (b) Determine the number of moles of NO, in the 27.50 mL of Solution B which remained unreacted at the end of the reaction.

Question

Solution A is 0.2400 M Ca(NO3)2(aq).
Solution A is diluted by a factor of 3 to form Solution B.

As2O3(s) reacts with NO3–(aq) to produce NO(g) and H3AsO4(aq)
When As2O3(s) was added to 27.50 mL of Solution B, 1.710 × 1021 molecules of NO(g) were
obtained from the reaction in 88.75% yield.
(a) If As2O3(s) was the limiting reactant, calculate the mass of As2O3(s) which reacted
with NO3–(aq).
(b) Determine the number of moles of NO3– in the 27.50 mL of Solution B which remained unreacted at the end of the reaction
