Achemist needs to create a 50% hcl solution. (hcl is hydrochloric acid. a "50% hcl solution" contains 50% hcl and the other 50% is water.) how much of a 70% hcl solution must be mixed with 30 ml of a 25% hcl solution in order to result in a 50% hcl solution? round your answer to 2 places after the decimal point (if necessary) and do not type any units (such as "ml") in the answer box.
