For metric unit conversions, figure out if you are going to go from a smaller measurement to a larger one, and vice versa. for small to large, divide by 10, 100, 1000 depending on how much different they are. ex 987 cm = 98.7 dm.
for large to small, multiply by 10,100, or 1000 depending. ex 987 km = 9870 hm.
Answer:
Fluorine gas reacts violently with water to produce hydrogen fluoride and ozone according to the following unbalanced equation. How many moles of o, are created assuming STP conditions are in effect, given
Explanation:

The structure of propylamine is pretty linear CH3-CH2 - CH2 - NH2.
The structur of trimethylamine is completely branched: a atom of N surroundeb by three CH3- radicals.
As theory predicts, in absence of other factors, longer chains have higher intermolecular forces (London forces) than branched compounds. So we must expect that propylamine has higher boiling point methyleamine.
You can verify that prediction with the literature. I did it: propylamine boiling point is 47-51°C while methylamine boiling point is 3 - 7°C.
Molarity is in units of moles/L. So you must determine the moles of CH3OH, then divide by the total volume.
To determine the moles of CH3OH, divide the weight in grams of CH3OH by the molecular weight
11.7g / 32g/mol = 0.366 mol CH3OH
0.366 mol CH3OH / .230 L = your molarity
Answer:
The volume of 15.0 grams of H2S at STP is 9.85 L.
Explanation:
1 unit of any gas under STP has volume 22.4 L.
Unit's mass M(H2S) = 2M(H) + M(S)= 2*1.0 +32.1=34.1 g/U
15g * 1U/34.1g= 0.440 U
0.440 U*1L/22.4L= 9.85 L
Hope this helped you :)
Good Luck :D
BTW, If you understand what I am saying and want the more technical answer, take all the (U) and replace it with (Mol) which is an abbreviation for Mole
:D have a good rest of your night
