How many moles of N₂O₅ are produced when 3.00g of O₂ react completely in the following equation? 2N₂ + 5O₂ → 2N₂O₅ A. 0.0375 B.
a_sh-v [17]

Answer: A. 0.0375

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} O_2=\frac{3.00g}{32g/mol}=0.094moles

2N_2+5O_2(g)\rightarrow 2N_2O_5

According to stoichiometry :

As 5 moles of O_2 give = 2 moles of N_2O_5

Thus 0.094 moles of O_2 give =\frac{2}{5}\times 0.094=0.0375moles  of N_2O_5

Thus 0.0375 moles of N_2O_5 will be produced when 3.00g of O₂ react completely
