Answer:

0.422 mol/L.

Explanation:

  • <em>Molarity (M)</em><em> is the no. of moles of solute dissolved in a 1.0 L of the solution.</em>

<em />

M = (no. of moles of glucose)/(volume of the solution (L))

M = (mass/molar mass)of glucose / (volume of the solution (L)).

∴ M = (mass/molar mass)of glucose / (volume of the solution (L)) = (289 g/342.2965 g/mol)/(2.0 L) = 0.422 mol/L.

Water vapor is not usually seen.
xeze [42]

Answer:

True

Explanation:

Water vapor is totally invisible.

Without it, there would be no clouds or rain or snow, since all of these require water vapor in order to form. All of the water vapor that evaporates from the surface of the Earth eventually returns as precipitation - rain or snow.
