Question 26

Using the equation for the decomposition of nitrogen trichloride:

2NCl3(l)→N2(g)+3Cl2(g) 2\text{NCl}_3(\text{l}) \rightarrow \text{N}_2(\text{g}) + 3\text{Cl}_2(\text{g}) 2NCl3​(l)→N2​(g)+3Cl2​(g)

calculate the maximum mass, in g, of nitrogen (N2\text{N}_2N2​) produced for every 1620 dm3 of chlorine (Cl2\text{Cl}_2Cl2​), measured at room temperature and pressure, produced in this reaction. (relative formula mass: N2=28\text{N}_2 = 28N2​=28;

1 mol of any gas at room temperature and pressure occupies 24 dm3)
