The difference of molarity and molality is in the units:
Molarity is expressed in mol solute / L solution;
<span> while Molality is
expressed in mol solute / kg solvent</span>
Since no other data is given, let us assume that the
contribution of methanol on the total volume is negligible. So that,
Molality = (20.3 mol / L) (1 L / 0.858 kg)
Molality = 23.66 m
<span>The closest answer is letter C. 23.7 m</span>
To try to get attention, it's not safe and you can get sent to the hospital. People think it's a joke, it's really not.
I haven't learned this yet but my friend did I'll text them and get back to you with the answer in a bit brb!
Metals are located on the left of the periodic table, and nonmetals are located on the upper right.
Explanation: Metals: Lustrous (shiny)
Good conductors of heat and electricity.
High melting point.
High density (heavy for their size)
Malleable (can be hammered)
Ductile (can be drawn into wires)
Usually solid at room temperature (an exception is mercury)
Opaque as a thin sheet (can't see through metals)
Nonmetals: High ionization energies.
High electronegativities.
Poor thermal conductors.
Poor electrical conductors.
Brittle solids—not malleable or ductile.
Little or no metallic luster.
Gain electrons easily.
Dull, not metallic-shiny, although they may be colorful
