Determine the mass percentage concentration of a solution prepared by dissolving 3.00 g of NaCl (58.44 g/mol) in 150 g of H20.

< 11 of 19 I Review Constants | Periodic Table Part B A student placed 16.0 g of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100. mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 45.0 mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100. mL of the final solution? Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) ? Value Units

What is a colligative property? O A property that depends on the number of particles in solution, but not on the nature of the particles. O A property that relates the temperature of a gas to the pressure of the gas. O A property that depends on the specific chemical behavior of the constituent elements and not on the amount in solution. O A property that can only be measured when the moles of gas are constant. O A property that enhances the solubility of a molecule in water.

The maximum quantity of lead allowed in drinking water is 0.05 ppm. What mass of lead could be found in 5,000 kg of water? mass Pb2+ = [?] g mass Pb²- DELL Enter

Consider a 1.000-L stock solution of 9.69 M Na3PO4. A 2.000-mL aliquot is taken from this stock solution and diluted to a final volume of 1.000 L. A 5.000-mL aliquot is then taken from this new solution and further diluted to make a new solution with a final volume of 750.0 mL.   Calculate Na+ in the final solution.

A sample of  copper(II) sulfate was created by measuring 57.73 g of solute and adding it to 1.6 L of water.  What is the concentration of the solution?
