3. Standard white vinegar you can buy in the grocery store is 5% concentration. That means 5% of the liquid vinegar is acetic acid and 95% of the solution is water. In a hardware store, you can buy industria strength vinegar, which is 30% concentration. This means that 30% of the vinegar is acetic acid, and the remaining 70% is water. Samuel does another experiment, this time with 5% vinegar and 30% vinegar. He sets up two science fair volcanoes (in no particular order), each with the same temperature, mass of baking soda and volume o vinegar. But one volcano uses 5% vinegar and the other volcano uses 30% vinegar. He measures the volume of gas production for the'first minute of each reaction, and he records the data below.
