The number of n atoms in 0.410 mol nh3

The number of nitrogen atoms in given moles of ammonia are

Explanation:

We are given:

A chemical compound having formula

Moles of ammonia = 0.410 moles

In 1 mole of ammonia, 1 mole of nitrogen atoms and 3 moles of hydrogen atoms are present.

According to mole concept:  

1 mole of compound contains number of atoms

So, 0.410 moles of ammonia molecule will contain = number of nitrogen atoms.

Hence, the number of nitrogen atoms in given moles of ammonia are

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
