The molecular formula for biomass is obtained by measuring the amounts of C, N, H, O, and other elements in cells. For a particular bacterial strain, the molecular formula was determined to be C4.4H7.301.2No.86. These bacterial cells are grown under aerobic conditions with hexadecane (C16H34) as substrate.

Onthou om te verduidelik presies hoe jy dit sal op maak.Phosphate buffered saline (PBS) is a physiological buffer often used in biology experiments. Because the concentrations are very low and small amounts are difficult to weigh out, it is often prepared as a 10X stock solution meaning that it is prepared at 10 times the working concentration which is 1X. 1X PBS is made up of Na2HPO4 10 mM (MW 141.9 g.mol-1); KH2PO4 8 mM (MW 136.08 g.mol-1), NaCl 137 mM (MW 58.44 g.mol-1) and KCl 74.5 mM (MW 74.5 g.mol-1). You decide to prepare a 1 L 10X solution of PBS. What is the Molar (M) concentration of each of the components in you 10X stock. Write your answers in the table below. How much of each of the components should you weigh out to prepare 1L of the 10X stock solutions. Write your answers in the table below.
