how much of 0.5normal fas is equal to molar
Your partial post makes no sense.
To determine how much of a 0.5 normal solution is equal to molar, we need to understand the concept of normality and molarity in chemistry.
Normality (N) is a measure of the concentration of a solute in a solution, based on its chemical equivalents. It is defined as the number of equivalents of a substance present in one liter of a solution. Normality is often used in acid-base chemistry.
Molarity (M) is another way to express the concentration of a solute in a solution. It is defined as the number of moles of a solute present in one liter of a solution. Molarity is commonly used in many areas of chemistry.
Since normality and molarity are different units of concentration, you cannot directly convert between them. Normality depends on the chemical reaction and the number of equivalents of a solute involved, while molarity is simply the number of moles of a solute in a given volume of solution.
To determine the equivalent molarity, you need to know the reaction in question. The stoichiometry of the reaction will allow you to calculate the number of equivalents of the solute involved. Once you have the number of equivalents, you can convert it to molarity.
For example, let's say you have a reaction where 1 mole of the solute is equivalent to 2 equivalents. If you have a 0.5 normal solution, it means you have 0.5 equivalents in one liter of solution. To calculate the molarity, you divide the number of equivalents (0.5) by the number of moles that 1 equivalent represents (2).
Therefore, the molarity in this case would be 0.5 equivalents / 2 moles = 0.25 M.
In summary, you cannot directly convert normality to molarity without knowing the stoichiometry of the reaction. Once you have the number of equivalents for the solute, you can calculate the molarity by dividing the number of equivalents by the number of moles per equivalent.
