Answer:
Avogadro's Law
Explanation:
Avogadro's number (6.23 x 10^23)
Avogadro's law states that the volume and number of moles are proportional if pressure and temp remain constant.
Molarity of a solution is the molar concentration, which is the number of moles of solute in 1 L of solution.
the mass of glucose is - 125 g
number of moles of glucose - 125 g / 180.16 g/mol = 0.694 mol
the number of moles of glucose in 650.0 x 10⁻³ L - 0.694 mol
number of moles of glucose in 1 L - 0.694 mol / 650.0 x 10⁻³ L = 1.068 mol/L
molarity of glucose solution is 1.068 M

They do not depend on the amount of substance you have.
No, the solid can not be frozen water. This is because water has a melting point of 32 degrees Fahrenheit. Room temperature is well above 32 degrees, so the solid would have begun to melt. Since the solid was not melting, we can infer that it is not water.
