How many moles of KF are contained in 347 g of water in a 0.175m KF solution?
This value is 0,06 moles.
How many moles of KF are contained in 347 g of water in a 0.175 m KF solution?
The definition of 0.175 m KF is that 1 kg of water contains 0.175 moles of KF. Thus, 347 g of water is equivalent to 0.347 kg, and to find moles of KF, you calculate as follows:0.175 moles/Kg x 0.347 kg = 0.0607 moles of KF are present (3 significant figures).
What is the Kf of water?
The Kf (freezing point depression constant) of water is approximately 1.86 °C/m. This means that for every 1 molal solution of a solute in water, the freezing point of water is expected to decrease by 1.86°C.
What concentration of aqueous NaOH solution freezes at -3.2ºC The freezing point of pure water is 0.0ºC and Kf of pure water is -1.86ºC m?
The change in freezing point is calculated as ΔTf = Kf * m, where Kf = -1.86°C/m for water. The change in temperature is -3.2°C - 0.0°C = -3.2°C. In this case, m = ΔTf / Kf = -3.2°C / -1.86°C/m = 1.72 m. Therefore, the concentration of NaOH solution is 1.72 mol/L.
What concentration of aqueous NaOH solution freezes at -32 degrees Celsius the freezing point of pure water is 00 degrees and kf of pure water is -186 degrees Celsius over m?
We can use the freezing point depression formula: ΔTf = Kf * m. Given ΔTf = -32°C, Kf = -1.86 °C/m, and ΔTf = i * m * Kf in which i = 2 for NaOH. Rearranging the equation, we get m = ΔTf / (i * Kf) = (-32) / (2 * -1.86) = 8.6 mol/L. Therefore, the concentration of the NaOH solution is 8.6 mol/L.
What does the kf reagent factor mean?
mgwater per ml will be called as KF factor. Means per ml of KF reagent contains this much of water. mgwater per ml will be called as KF factor. Means per ml of KF reagent contains this much of water.

What is kf factor?
The kf factor, or soil permeability factor, is a measure of a soil's ability to conduct water. It is used in hydrology and geotechnical engineering to calculate the rate of water flow through soil. A higher kf factor indicates greater permeability and faster water flow.
What is the mole fraction of 58 g of KF dissolved in 180 g of water?
1/11 is the mole fraction of 58 g of KF dissolved in 180 g of water.
What is 1566 in kf factor formula?
In the context of the KF (Karl Fischer) titration formula, the value "1566" typically refers to the milligrams of water per mole of the reagent used (often iodine) in the titration. The KF factor can be calculated using this value to determine the water content in a sample. To convert the KF factor to a more usable form, you would generally express it in terms of milligrams of water per milliliter of titrant, factoring in the concentration of the KF reagent used.
What are the six principles of management?
The KF is greater than the sum of its partsOwnership of the KF is dispersedPower in the KF flows down…and upThe KF is held together by reputation, not controlThe KF runs on information technologyThe KF is a business
How do you solve 5.167 equals log Kf How to find the value of Kf?
If log(Kf) = 5.167 then Kf = 105.167 = 146,983 (approx).
