This molarity is approx. o,89.
To make a 0.5 M solution of potassium dihydrogen orthophosphate (KH2PO4), you would need to weigh out 13.5 grams of KH2PO4 and dissolve it in water to make 1 liter of solution. Be sure to use a balance to accurately measure the amount of KH2PO4 needed for the desired molarity.
68 mL = 2.3 US fluid ounces.
Using the ideal gas law, we can calculate the number of moles of gas present in the 15 L volume at 100°C and 1 ATM. Next, we can determine the molecular weight by dividing the given mass (68 g) by the number of moles obtained.
The solubility of potassium chloride (KCl) in water is approximately 34 grams per 100 mL at room temperature. Therefore, in 200g of water, the maximum amount of KCl that can dissolve is around 68 grams.
Benzoic acid is sparingly soluble in water, with a published solubility of approximately 3.4 g/L at room temperature. To dissolve 1 gram of benzoic acid, you would need at least around 0.29 L or 290 mL of water.
To make a 0.5 M solution of potassium dihydrogen orthophosphate (KH2PO4), you would need to weigh out 13.5 grams of KH2PO4 and dissolve it in water to make 1 liter of solution. Be sure to use a balance to accurately measure the amount of KH2PO4 needed for the desired molarity.
