Consider the reaction:

Question

3Ba(s)+N2(g)--->Ba3N2(s)

1)How many moles of barium metal react to produce 0.190 mol of barium nitride?

2)How many moles of nitrogen gas react?

Answer 1

Use the coefficients in the balanced equation to convert moles of one substance to moles of another..
0.190 mole Ba3N2 x (3 moles Ba/1 mole Ba3N2) = 0.190 x 3/1 = ?
