Answer to Question #241934 in General Chemistry for Thakasile

Question

Briefly explain how you would prepare the 0.155mol.dm^-3 potassium hydroxide solution in the laboratory

Answer 1

Generally, in many solutions, the weight is given in grams and volume is given in milliliters or liters. At this point, it is important to establish the relation between the units of weight and volume. One kilogram (weight) of water at a temperature of maximum density and under normal atmospheric pressure has the volume of one liter. This means that one kilogram (weight) of water equals one liter of volume, and one gram of water by weight equals one milliliter of water by volume. Thus the units of weight (gram) and volume (ml) are similar and interchangeable.
