Remark
Ammonium Nitrate decomposes as follows.
NH4NO3 → N2O + 2H2O
If this does not agree with the reaction you have, let me know.
Step One
Find the molecular Mass of Ammonium Nitrate.
N = 1 * 14 = 14
H = 1 * 3 = 3
N = 1 * 14 14
O3 = 3<u>*16 = 48</u>
Molar Mass =69
Note: the masses used are approximate. Every periodic table is different. When you answer this question use the masses on your periodic table. My numbers are just guides.
Step Two
Find the number of mols in Ammonium Nitrate.
<u>Formula</u>
mols = given mass / molar mass
<u>Givens</u>
given mass = 3.14
Molar Mass = 69
mols = 3.14 / 69
mols = 0.0455
Step 3
moles of water.
1 mol of Ammonium Nitrate = 2 mols of water
0.0455 mols of Ammonium Nitrate = x mols of water
x = 2* 0.0455 mols of water.
x = 0.091 mols of water
Step 4
Find the molecules of water.
1 mol of water = 6.02*10^23 molecules of water
0.091 mol water= x
x = 0.091 * 6.02*10^23
x = 5.48 * 10^23
Answer:
Technology is the use of reliable knowledge for a practical purpose.
Ecology is the study of the natural world through observation and experimentation.
Explanation:
I don't know much about this, but probably the reason why your teacher circled 300k is because of what's in the photo below. If you couldn't tell from the photo, its because 300k isn't negative. Anyway this is my guess, based on my limited knowledge.
