A chemist mixes 175 millilters of solution that is 62% acid with 75 milliliters of pure acid. What percentage of the resulting Mixture is acid

  73.4%

Step-by-step explanation:

The ratio of acid to mixture volume is ...

  (0.62·175 +1.00·75)/(175 +75) = 183.5/250 = 0.734 = 73.4%

73.4% of the resulting mixture is acid.
