0.81 mol

Explanation:

Since the mole ratio of Ba : BaN2 = 3 : 1 (which can be seen from the balanced equation)

Therefore, 3 moles of Barium metal will produce 1 mole of BaN2.

With this ratio, let the no. of moles of barium metal be x.

$\frac{3}{1} = \frac{x}{0.270} \\x = (0.2703)(3)\\x = 0.81 mol$
