In the balanced chemical reaction, the coefficients represent the mole relationship of each substance needed or produced in the reaction. These coefficients can be used to show the relationship between only two substances and when written as a ratio (x mols of A / y mol of B) it is called the molar ratio. What is the molar ratio between sodium sulfate and sulfuric acid?
An aqueous solution containing 5.85g of an optically pure compound was diluted to 800.0mL with water and placed in a polarimeter tube 10.0cm long. The measured rotation was -5.93degrees at 25degrees C. Calculate the specific rotation of the compou..
