7. Phosphate Buffered Saline (PBS) buffer requires three components; 0.0017M KH2PO4, 0.0052M Na2HPO4, and 0.15M NaCl. Calculate the volume of stock solution needed for each component in order to make 1L of PBS. Below are the stock solution concentrations for each component. Finally, include the amount of dH20 needed to bring the solution up to 1 L. Show all calculations. 1.7M KH2PO4 stock solution
5.2M Na2HPO4 stock solution
1.5M NaCl stock solution​

The phlogiston theory in the 17th century attempted to explain burning. the theory stated that combustable objects contained a material called phlogiston, a substance without mass, color, odor, etc. after objects burned, the objects were dephlogistonated and were then in their true form. the phlogiston theory was accepted until the 18th century, when lavoisier proved that combustion requires a gas that has mass. phlogiston is considered a) to be scientific knowledge b) not to be scientific knowledge c) to be proven by scientific method d) to be accepted in the modern scientific community
