The concentration of water vapor in ppm is 2.5×10⁴
given percentage of water vapor 2.5
This means that 2.5 g of solute is present in 100 g of solution.
ppm refers to part per million in this case total gram of solute to 10⁶ gram of solution
therefore, it implies 2.5×10⁴ g of solute is present in 10⁶g of solution and therefore concentration in ppm will be 2.5×10⁴.
we can also use general formula for the conversion
ppm = mass percentage × 10⁴
