How many moles of N₂O contain the same number of nitrogen atoms as 4.60 g of NO₂? A)0.500 B)0.0500 C)0.100 D)0.200

Question

Quizplus · Accepted Answer

First, calculate the molar mass of N2O (Nitrogen = 14.01 g/mol, Oxygen = 16.00 g/mol, so N2O = 2*14.01 + 16.00 = 44.02 g/mol). Then, find the number of moles of N2O in 4.60 g (4.60 g / 44.02 g/mol = 0.1045 moles). Since each molecule of N2O contains two nitrogen atoms, the number of moles of nitrogen atoms in 4.60 g of N2O is 0.1045 moles * 2 = 0.209 moles. To have the same number of nitrogen atoms in N2O, you need 0.209 moles of nitrogen atoms. Since each molecule of NO contains one nitrogen atom, you need 0.209 moles of NO, which is option B (0.0500 moles is incorrect; the correct calculation leads to 0.209 moles, but the question seems to have been misinterpreted in the setup).
