PERCENT SOLUTIONS Many chemical solutions are mixed as percent concentrations. When working with a dry chemical, the percent is calculated as grams dry chemical in 100 ml. This is known as a weight/volume or W/V formula. 0.9% (w/v) NaCl solution is ………. g NaCl in ………. ml water. When the formula includes a liquid chemical, then the percent solution is volume added chemical in ml made up to 100 ml with solvent. 10% (v/v) acetic acid solution in water is ………. ml glacial acetic acid added to ………. ml water.
