Answer 1

238 grams of ammonia will be produced at STP.

Given:

Moles of nitrogen=7

Chemical reaction:

$N_2+3H_2----->2NH_3$

From the reaction, we can say that:

1 moles of N₂ produces 2 moles of NH₃,

So, 7 moles of N₂ will produces 7*2=14 moles of NH₃.

Now, Moles of NH₃= 14 moles

Molar mass of NH₃ = 17g/mol

To find:

Mass of NH₃=?

Number of moles:

It is defined as the ratio of given mass over molar mass.

$\text{Number of moles} =\frac{\text{Given mass}}{\text{Molar mass}} \\\\\text{ Mass}=\text{Number of moles}*\text{Molar mass}\\\\\text{ Mass}= 14*17g/mol\\\\\text{ Mass}=238 g$

238 grams of ammonia will be produced at STP.
