Mass percent = % (m/m) = (grams of solute/grams of solution) x 100. Solution, not solvent so you need to add them. % (15 g / 15 g + 235 g) x 100 = 6.0% Na2CO3. An IV solution is prepared by dissolving 25 g glucose (C6H12O6) in water to make 500 mL solution.
âActivated B cells differentiate into either antibody generating factories called plasma cells that secrete soluble antibody, or into memory cells that survive in the body for years afterwards to allow the immune system to remember an antigen and respond faster upon future exposures.â ~ Wikipedia...
Anemia â Normal red blood cells live for about 120 days. Sickle cells are fragile and only live for 10-20 days, and the body cannot make enough new cells to compensate. This leaves people with sickle cell disease chronically short on red blood cells to carry oxygen to their tissues.
