What is the molarity of pure liquid benzene?
Molarity is a concentration unit of solutions, pure benzene is not a solution so this term is meaningless for a pure liquid. In other words: Molarity of a solution is a numerical way of saying exactly how much solute is dissolved in a solvent .Molarity is equal to the moles of solute divided by the liters of solution. Molarity of a solution can be calculated by using the following formula: M= moles of solute/liters of solution
Why is the symbol for the element sulfur different from the formula for a molecule of sulfur?
why is the symbol for the element sulfur different from the formula fod a molecule of sulfur
What is a solution and what are the 2 basic parts of a solution?
solute is the substance being dissolved, solvent is the substance doing the dissolving. A solution is a mixture, not a compound. There is no exact formula for a solution, there can be a small amount dissolved (called a dilute solution) or a large amount dissolved (called a concentrated solution). Sugar in water is a solution, sugar is the solute, water is the solvent.
