The mole fraction of carbon dioxide (xco2) in water is 0.25. determine the molarity of co2. (assume the density of the solution is 1.0 g/ml.)

Let us assume that there is 1 mole of the solution present. The mass becomes:

Mass = fraction of carbon dioxide * Mr of carbon dioxide + fraction of water * Mr of water

Mass = 0.25*44 + 0.75*18

Mass = 24.5 grams

Now, we determine the volume of the solution using:

Volume = mass / density

Volume = 24.5/1 = 24.5 mL

The molarity of a solution is:

Molarity = moles / liter
Molarity = 0.25 / 0.0245

Molarity = 10.2 M

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
