How many grams of n2 are required to produce 240.0g nh3?

The mass of required are, 198 grams.

Explanation : Given,

Mass of = 240.0  g

Molar mass of = 17 g/mol

First we have to calculate the moles of .

Now we have to calculate the moles of

The balanced chemical equation is:

From the reaction, we conclude that

As, 2 mole of produces from 1 mole of

So, 14.12 mole of produces form mole of

Now we have to calculate the mass of

Molar mass of = 28 g/mole

Therefore, the mass of required are, 198 grams.
