Answer:
Explanation:
Heat and temperature are two different but closely related concepts. Note that they have different units: temperature typically has units of degrees Celsius ( ∘ C ^\circ\text C ∘Cdegrees, start text, C, end text) or Kelvin ( Kstart text, K, end text), and heat has units of energy, Joules ( Jstart text, J, end text).
The corresponding value for kW, the ionization constant for water, would be 1.00 X 10^-14 at T = 25 degrees Celsius. This is an equilibrium value for the self process or ionization and or dissociation of water.

The percent given is in terms of volume so the solution contains 40 mL of alcohol per 100 mL of the solution. Multiplying the given amount of solution to the percentage, we will obtain the amount of alcohol.
620 mL solution ( 40 mL alcohol / 100 mL solution ) = 248 mL alcohol
Answer:
By adding 500 g or 0.5 kg of glucose to water until a volume of 1 L.
Explanation:
Hello,
In this case, since the mass-volume percent is computed taking into account the mass of solute and the volume of solution:
In order to make a 1-L solution, we must measure out the following mass of glucose:
By using a balance and subsequently mix it into a 1-L flask in order to prepare it.
Best regards.
