Question

Based on the balanced equation, if 60.1 grams of Nitrogen (N2) are used, how many grams of ammonia (NH3) is made?

3 H2 + 1 N2 ----> 2 NH3 ​

Answer 1

73.07 grams of ammonia is produced.

Step-by-step explanation:

In order to find the grams of ammonia produced, we need to find the amount of the reactants so that we know how much product (ammonia) the reactants (Hydrogen and Nitrogen) can and will produce.

First, we need to use the balanced equation to find the amount of moles equivalent to the 60.1 grams of Nitrogen that reacts.

To convert from Grams to Moles, we will divide by the molar mass (amu)..

60.1 grams of N2 / 2(14.01) grams N2 = 2.144896502 moles of N2.

So, we know that 60.1 grams of N2 equals 2.144896502 moles.

Now, we will look at the balanced equation and convert from moles of N2 to moles of NH3 in order to later find the grams of NH3 (ammonia) produced..

2.144896502 moles N2 * 2 moles NH3/1 mol N2 = 4.289793004 moles NH3.

Now that we know the amount of moles produced of ammonia, we will convert to grams. We can do this by multiplying by the molar mass of ammonia which is 17.034 (N = 14.01, H = 1.008, ---> 14.01 +3(1.008) = 17.034)

4.289793004 moles NH3 * 17.034/1 mol = 73.07233403 grams NH3

This can be estimated to 73.07 grams of NH3 (ammonia) produced.

Answer 2

mass NH₃ produced = 72.9g (3 sig. figs.)

Step-by-step explanation:

3H₂ + N₂ => 2NH₃

given excess 60.1g (?)grams

moles => (60.1g/28g/mol)

= 2.15mole => 2(2.15mole)

= 4.29mole NH₃

mass NH₃ = 4.29moles x 17 g/mole = 72.9grams NH₃

Always convert given data into moles, solve in terms of moles and convert to needed dimension from mole yields. :-)
