To find the grams of sodium azide (NaN3) required to produce 5.00 grams of nitrogen (N2), we first calculate the moles of N2 produced. The molar mass of N2 is approximately 28.02 g/mol, so 5.00 grams of N2 is about 0.1786 moles (5.00 g / 28.02 g/mol). According to the reaction, 2 moles of NaN3 produce 3 moles of N2. Therefore, 0.1786 moles of N2 corresponds to 0.1191 moles of NaN3 (0.1786 moles N2 * 2/3). Finally, using the molar mass of NaN3 (approximately 65.01 g/mol), we find that 0.1191 moles of NaN3 is about 7.75 grams (0.1191 moles * 65.01 g/mol). Thus, approximately 7.75 grams of NaN3 are required.
