How to Make a Solution: Chemical, Molar and Weight Percent

For example, an experiment calling for 50 g of a solvent and 250 ml of water can be scaled down by a factor of 10 so that it uses only 5 g of solvent and 25 ml of water. You can make scaling down easier by using smaller beakers, test tubes, and other measuring equipment. When making chemical solutions, always use the appropriate safety equipment.
