Formula for calculating the concentration of chemical substance
Chemical quantitative analysis of substance concentration often involves the preparation of solution and the calculation of solution concentration. It is more convenient to express the composition of solution by substance concentration when using chemical reaction for quantitative analysis
Conversion of mass percent concentration to volume percent concentration
4.0% (w / W) hydrochloric acid 100g is equal to what volume percentage (V / V) hydrochloric acid
Do you want to calculate the volume of hydrogen chloride gas that can be dissolved in a liter of 4% hydrochloric acid solution? If so, you must first know the density of 4% hydrochloric acid. After investigation, the density of 4% hydrochloric acid is 1.02 g / ml, then the concentration of this hydrochloric acid is: C = 1000 × 1.02 × 4% / 36.5 = 1.117
