what is the mass of nh4cl that must dissolve in 100. grams of h2o to produce a saturated solution at 70 degrees celsius
To calculate the mass of NH4Cl that must dissolve in 100 grams of H2O to produce a saturated solution at 70 degrees Celsius, you would need to know the solubility of NH4Cl in water at that temperature.
Unfortunately, I do not have the specific solubility values programmed into my database. However, I can provide you with the general steps to solve this problem:
1. Look up the solubility of NH4Cl in water at 70 degrees Celsius. This information can typically be found in reference books or online sources.
2. Once you have the solubility value, convert it to grams per 100 grams of water (g/100g H2O). This will give you the maximum amount of NH4Cl that can dissolve in 100 grams of water at that temperature.
3. Subtract the initial mass of water (100 grams) from the maximum mass of the resulting solution to determine the mass of NH4Cl needed. This will be the mass of NH4Cl required to saturate the solution.
Please note that the solubility of NH4Cl in water can vary depending on factors such as temperature and pressure, so it's important to use accurate solubility data for the specific conditions given in the problem.
To find the mass of NH4Cl that must dissolve in 100 grams of H2O to produce a saturated solution at 70 degrees Celsius, we need to know the solubility of NH4Cl at that temperature.
Unfortunately, the solubility of NH4Cl in water varies with temperature. To find the solubility at 70 degrees Celsius, we will need to consult a solubility table or look it up in a reliable source.
Let's assume that the solubility of NH4Cl at 70 degrees Celsius is 40 grams per 100 grams of water. This means that at this temperature, 100 grams of water can dissolve a maximum of 40 grams of NH4Cl.
However, since we want a saturated solution, we need to add exactly the amount of NH4Cl that will bring the solution to its maximum solubility. Therefore, we need to add 40 grams of NH4Cl to 100 grams of water at 70 degrees Celsius to produce a saturated solution.
Remember to double-check the solubility values for NH4Cl at 70 degrees Celsius in a reliable source, as this answer is based on the assumption provided.
