Answer:
448g
Step-by-step explanation:
First, we'll begin by writing the balanced equation for the reaction. This is illustrated below:
3NaOH + 2NBr3 → N2 + 3BrNa + 3HBrO
Next, we shall determine the number of mole of N2 produce by the reaction of 48 moles of NaOH.
This is illustrated below:
From the balanced equation above, 3 moles of NaOH produced 1 mole of N2.
Therefore, 48 moles of NaOH will produce = 48/3 = 16 moles of N2
Finally, we shall convert 16 moles of N2 to grams. This can be achieved as shown below:
Number of mole of N2 = 16 moles
Molar Mass of N2 = 2x14 = 28g/mol
Mass of N2 =?
Mass = number of mole x molar Mass
Mass of N2 = 16 x 28
Mass of N2 = 448g.
Therefore, 448g of N2 is produced from the reaction.
