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

Answer:
Explanation:
The magnitude of the net force exerted on q is known, we have the values and positions for and q. So, making use of coulomb's law, we can calculate the magnitude of the force exerted by on q. Then we can know the magnitude of the force exerted by about q, finally this will allow us to know the magnitude of
exerts a force on q in +y direction, and exerts a force on q in -y direction.
The net force on q is:
