With the Haber process, how many grams of hydrogen will be needed to make 0.3820 pounds of ammonia? Needed to 3 decimal places for pounds to grams conversion.

I’m having a mental block on part of this and would greatly appreciate help! Thanks!

30.576 g of hydrogen

Explanation:

First we need to covert the pound in grams.

if 1 pound is equal to 453.592 grams

then 0.3820 pounds is equal to X grams

X = (0.3820 × 453.592) / 1 = 173.272 grams

So we have 173.272 grams of ammonia.

Now we look at the chemical reaction where hydrogen (H₂) reacts with nitrogen (N₂) to produce ammonia (NH₃):

3 H₂ + N₂ → 2 NH₃

number of moles = mass / molar weight

number of moles of ammonia = 173.272 / 17 = 10.192 moles

Now taking in account the chemical reaction, we formulate the following reasoning:

if 3 moles of hydrogen produce 2 moles of ammonia

then Y moles of hydrogen produce 10.192 moles of ammonia

Y = (3 × 10.192) / 2 = 15.288 moles of hydrogen

mass = number of moles × molar weight

mass of hydrogen = 15.288 × 2 = 30.576 g
