the mole fraction of carbon dioxide (xco2) in water is 0.25. what is the mass fraction of co2 in this solution? determine the molarity of co2 in the solution (assume the density of the solution is 1g/ml).

Respuesta :

The molarity of carbon dioxide is 10.2 m.

Equation :

assuming there is a single mole of the solution in the system. The mass changes to:

Mass is equal to the product of a proportion of carbon dioxide and a unit of water.

Mass = 0.25x44 + 0.75x18

gram mass = 24.5

Now, we use: to calculate the solution's volume:

Mass x density equals volume.

Volume = 24.5/1

Vol = 24.5 mL.

A solution's molarity is:

Molarity = moles per liter.

Molarity equals 0.25 / 0.0245

Molarity = 10.2 m

Molarity :

In terms of the amount of substance per unit volume of solution, molar concentration is a measurement of the concentration of a chemical species, specifically a solute in a solution. The most common measure of molarity in chemistry is the number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units.
