hi, ive been trying to figure out how to do some limiting reactant problems (stoic), i have to use dimensional analysis but i have no idea how to set it up using that method, so i watched some khan academy vids, but i want to check to make sure im doing my homework right...
77.3 g of nitrogen and 14.2 grams of hydrogen react. determine the maximum mass of ammonia that can be produced?
what i did:
77.3/28=2.76 2.76 mol of nitrogen
14.2/6=2.37 2.37 mol of Hydrogen
there's 3 mol of Hydrogen for every 1 mol of Nitrogen, so hydrogen is the limiting reactant
2.37/2.76=.858 .858 mol of hydrogen for 1 mol of nitrogen (idk why i did this)
2.37(2/3)= 1.58 1.58 mol of ammonia
1.58(17/1)= 26.86g of ammonia
answer: maximum of 26.86g of Ammonia can be produced
can someone check this? i may also post more questions if i have them, thank you to anyone who can *delete me*
