The number of atoms contained in 16.0 grams of Mg would be the same as the number of molecules contained in ________ grams of N₂O.

Question

Quizplus · Accepted Answer

16.0 grams of Mg is 1 mole (since the molar mass of Mg is 24.305 g/mol). The molar mass of N2O is 44.01 g/mol, so 1 mole of N2O weighs 44.01 grams. To have the same number of molecules as atoms in 1 mole of Mg, you need 1 mole of N2O, which is 44.01 grams. However, the closest option is 29.0 grams, which is incorrect. The correct calculation should be based on the molar mass, but the problem seems to have an error in options.
