Answer these following questions please A) T.S.P. is an all purpose cleaner that can be used to clean driveways. What volume of solution would you get if you dissolved 150.0 g of sodium phosphate with water to produce a 0.23 mol/L solution? B) A "sports drink" contains 50 mg of sodium ions and 55 mg of potassium ions per 400 mL serving. Calculate the concentration of the sodium and potassium ions in ppm. C) What concentration results from mixing 400 mL of a 2.0 mol/L HNO3 solution with 600 mL of a 3.0 mol/L HNO3 solution?

How do I calculate the mass of Na2CO3 needed for the .25 ml of solution? Use the following image to help

1. What is the molarity of the solution that contains 0.050 g of aluminum nitride AIN in 22.5 L of solution? 2. Calculate the number of moles of NaCl solute present in 335 ml of 20.0 M NaCl solution 3. How much NaCl (s) do you need to prepare 435 mL of a 2.5 % (m/v) NaCl solution? 4. The hydronium ion concentration in a given solution is 1.8 x 104. What is the concentration of the hydroxide ions solution. What is the pH of the above solution.

Suppose a semipermeable membrane separates compartments A and B.   Both compartments contain solutions.  The levels of the solutions are equal initially.  Answer the following questions based on this information.  Each question is a separate question.    a.  If compartment A contains a 10% sugar solution and compartment B contains a 5% sugar solution, in which compartment will the volume level rise? b.  If compartment A contains a 2% sugar solution and compartment B contains an 10% sugar solution, which solution (2% or 10%) will exert the lower osmotic pressure?
