Answer:
Hey!I will try to help with the ones I know.
solubility is a means of comparing the extent to which different solutes can dissolve in a particular solvent at a definite temperature.
A saturated solution of a solute at a particular temperature is one which contains as much solute as it can dissolve at that temperature in the presence of undissolved solute particles....
This is what I know I hope it helps you
-2 for O
-1 for F
0 for N2
+1 for Li
+3 for Fe
Molar mass of NaOH = 39.997 g/mol
39.997 g ---------- 6.02x10²³ molecules
g --------------- 2.30x10²² molecules
mass = 2.30x 10²² * 39.997 / 6.02x10²³
mass = 9x199^24 / 6.02x10²³
mass = 15.280 g
hope this helps!
Answer:In the winter the polar jet moves south and becomes stronger because the North Pole gets colder but the equator stays about the same temperature. This increases the temperature contrast and moves the strengthened polar front jet farther south.
Explanation:
Find the molar mass of CH3 and divide that by 45.0. That should give a whole number and then mult that whole number by CH3 to find molecular formula to get like ( incorrect ex: C2H6) which is mult by 2
