WebThe absolute numbers of RGC-5 cells in 10% FBS were significantly higher than those under the serum deprivation condition at 48 hours (P=1.5×10 –9) and 72 hours (P=1.9×10 –7). These results suggest that Tet has little effect on cells that are growing rapidly in 10% FBS, but can protect cells under stressed conditions.
WebDec 30, 2024 · You have added 49.00 × 10-3 L × 0.100 M NaOH = 4.90 × 10-3 moles of OH- ions. Then it remains 5.00 × 10-3 - (4.90 × 10-3) = 1.0 × 10-4 moles H+. The H + concentration is 1.0 × 10-4/ (0.049 L + 0.050 L) = 1.0 × 10-4/ (0.099 L) = 1.00 × 10-3 M. As pH = -log [H+], pH will be 3.
