Final answer:
To convert 20g of N2O into 1 mole, you can use the given conversion factors and molar mass of N2O.
Step-by-step explanation:
To convert 20g of N2O into 1 mole, we can use the given conversion factors: 1 mole NH4NO3 to 1 mole N2O. Since the molar mass of N2O is 44.02 g/mol, we can set up the conversion as follows:
20 g N2O x (1 mole N2O/44.02 g N2O) = 0.4545 mole N2O
Therefore, 20g of N2O is equivalent to approximately 0.4545 moles of N2O.
