HEY MATES!!!GIVE A SIMPLE DEFINATION OF:
1) EQUIVALENT WEIGHT
2)MOLALITY
3)MOLARITY
Answers
Answer:
1. the mass of a substance especially in grams that combines with or is chemically equivalent to eight grams of oxygen or one gram of hydrogen : the atomic or molecular weight divided by the valence.
2. MOLALITY is a property of a solution and is defined as the number of moles of solute per kilogram of solvent. The SI unit for molality is mol/kg. A solution with a molality of 3 mol/kg is often
described as “3 molal” or “3 m.” However, following the SI system of units, mol/kg or a related SI unit is now preferred.
3.The MOLARITY of a solution is calculated by taking the moles of solute and dividing by the liters of solution. This is probably easiest to explain with examples. Example 1: Suppose we had 1.00 mole of sucrose (it's about 342.3 grams) and proceeded to mix it into some water. It would dissolve and make sugar water.
