Solute KMnO4 Soluble/Not Soluble in Water (A.1) Cyclohexane (A.2) Identify the Solute as Polar or Nonpolar (A.3) Sucrose Vegetable oil NaCl is soluble in water, but I, is not. Explain. State the general solubility rule concerning the polarities of a solute and solvent. Calculations B.4 Solubility is expressed as the number of grams of solute in 100 mL of water. Because you used a sample of 5.0 mL of water, the mass of the solute you measured out and the...
Concentrations of solute in solvent, whether in saturated solutions or not, can be expressed in many ways (molarity, molality, ppm, percent by mass, etc.). Molarity = moles of solute / liter of solution molality = moles of solute / kg of solvent ppm = mg solute / liter of solution ppb = microgram of solute / liter of solution %-by-mass = (grams of solute / grams of solution) x 100% To convert from %-by-mass to Molarity, assume 100g of solution,...

What mass (kg) of the solvent water should be added to 429 g of the solute tetrahydrofuran to generate a solution that contains 8.70 % by mass C4H8O. Molar Mass (g/mol) - C4H8O 72.12 - H2O 18.015 Density (g/mL) - C4H8O 0.8892 - H2O 0.9982 Name/Formula - tetrahydrofuran / C4H8O - water / H2O
hey i really need help for the molality to mass question. the
solvent is water and 100g. SOS!

If 1 kg of solvent (water) and 10 g of a solute (unknown) were mixed and the boiling point determined to be 101.8 degrees Celsius, calculate the molecular weight of the solute. Assume the water boiled at 100 degrees Celsius before solute was added.
1. Solubility in WATER Check solubility of four solutes in water (H2O). For each solute record how many teaspoons dissolved in 1/2 cup of water. NaCl: Start out with 4 small glasses (cups) and add 1/2 cup of water to each. Put 1/2 level teaspoon (tsp) of salt (NaCl) into the first cup and stir. If it dissolves within 1 minute; add another 1/2 tsp of salt and stir. Count the number of 1/2 tsps you are adding. Repeat until...
An aqueous salt solution is formed by adding 61.65 g Iron (III) nitrate (solute) to water (solvent). What mass (in g) of water is used if the freezing point of the solution is -11.8 oC. Kf H2O = 1.86 oC/m
