Problem 64E

To what volume should you dilute 25 mL of a 10.0 M H2SO4 solution to obtain a 0.150 M H2SO4 solution?

Step-by-Step Solution:
Step 1 of 3

Solution: Here, we are going to calculate the mass of sodium chloride to be added to the blood to bring the sodium ion concentration yo 0.138 M. Step1: In order to calculate the required mass of sodium chloride, we need to calculate the mass of sodium ion required to bring its concentration up to 0.138 M. We will do this using the concept of molarity. Molarity is defined as the number of moles of the solute(Here Na ion is the solute) in 1 litre of the solution. Mathematically, Number of moles of solute Molarity(M) = -------------------------------------- ------(1) Volume of solution in litres Step2: Now, required change in molarity of the sodium ion in human blood = (0.138- 0.118) M = 0.020 M Volume of the blood in litres = 4.6 L From equation (1), we get, number of moles of Na ion = Volume of blood in L X Molarity Na ion = 4.6 L X 0.020 M = 0.092 moles. Step3: Now, 1 mole of Na ion is produced by 1 mole of NaCl(sodium chloride) i.e., 1 mole of Na ion = molar mass of NaCl Therefore, 0.092 moles of Na ion = 0.092 X molar mass of NaCl ion = 0.092 x 58.4427 g [molar mass of NaCl = 58.4427 g] = 5.38 g Thus, the required mass of sodium chloride is 5.38 g. ------------------
