(a)
To determine: The number of molecules of NaCl present in 1L of solution of 1.0M NaCl having 58.5g of salt per liter.
Introduction: Molarity of a solution is defined as the number of moles of solute present in 1 liter of solution. The unit of molarity is mol/L. The molarity of the solution is used to express the concentration of the solution.
(b)
To determine: The number of millimoles of NaCl presents in the solution of 1.0M NaCl containing 58.5g of salt per liter.
Introduction: The mole is the SI unit that measures the amount of a substance. One mole is equal to the
(c)
To determine: The number of equivalents of sodium ions present in the 1.0M solution of NaCl.
Introduction: The concentration of ions present in a solution is expressed as the number of equivalents per liter. One equivalent is equal to the number of charges carried by one molarity of ions.
(d)
To determine: The percent solution of 58.5g of NaCl per liter.
Introduction: The concentration of the solute in a solution is expressed by percent solution. It means a 10% solution is 10 parts of solute in 100 parts of solution. The amount of solute in a percent solution is expressed as the percentage of total solution weight or volume.

She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D. Plasmodium falciparumarrow_forward
