What is the molal concentration of a solution that is prepared by dissolving 56.1 g of glucose in 285 g of water? The molar mass of glucose is 180.16 g/mol. Enter your answer with no units.

Enter your answer in the provided box. Calculate the percent by mass of the solute in the following solution. 4.00 g of toluene in 23.0 g of benzene %

A student dissolves 8.0 g of phenol (CH₂OH) in 125. mL of a solvent with a density of 1.06 g/mL. The student notices that the volume of the solvent does not change when the phenol dissolves in it. Calculate the molarity and molality of the student's solution. Round both of your answers to 2 significant digits. molarity molality = x10 DO 0x0

If 25.6 mL of methanol is dissolved in 87.1 mL of water, determine the percent by volume of methanol in the solution. (Do not enter a unit!)

Calculate the number of moles of solute present in 55.0 mg of an aqueous solution that is 1.40 m NaCl. Assume that for dilute aqueous solutions, the mass of the solvent is the mass of solution.

A student dissolves 8.3 of phenol (CH,OH) in 325. mL of a solvent with a density of 1.12 g/mL. The student notices that the volume of the solvent does not change when the phenol dissolves in it. Calculate the molarity and molality of the student's solution. Be sure each of your answer entries has the correct number of significant digits. molarity x10 molality 미

A solution was made by dissolving 10.000 g of NaCl (58.44 g/mol) in 150. mL (assume 1g/mL) of water.  What is the molality of the solution?

The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H,O). -6 Note: "major" chemical species are those present in concentrations greater than 10 mol/L. major species present when dissolved in water compound formula 0,0,.. nickel(II) chloride NiCl, sodium nitrate NaNO3 nickel(II) iodide Nil,
