Question

A particular experiment requires 13.5 µl hydrochloric acid solution. if 250 ml of hydrochloric acid solution is available, how many times can the experiment be performed? (note: 1ml = 1,000 µl.) about 18 about 18,500 about 18,500,000

Answer 1

Here, we're given a very simple unit conversion problem.

1 mL= 1 x 10⁻³ L

1 μL = 1 x 10⁻⁶ L

So, we can convert 250 mL and 13.5 μL into L as follows,

        250 mL = 250 x 10⁻³ L

        13.5 μL = 13.5 x 10⁻⁶ L

1 experiment requires 13.5 μL  of HCl.

Hence,

  the number of experiments = total volume / volume per experiment

                                                  = 250 x 10⁻³ L / 13.5 x 10⁻⁶ L

                                                  = 18518.518

                                                  = 18518

(number of experiments should be a whole number. Hence we have to choose 18518)

Hence, the number of experiments which can be performed is about 18500.

More about hydrochloric acid

• There are various uses for hydrochloric acid. In addition to electroplating, it is utilized in the manufacture of chlorides, fertilizers, and dyes as well as in the textile, rubber, and photography industries.
• Hydrochloric acid is corrosive to mucous membranes, the skin, and the eyes.
• Acute (short-term) inhalation exposure may result in pulmonary edema, ocular irritation, and inflammation of the respiratory tract, nose, and eyes in people.
• The mucous membranes, esophagus, and stomach may corrode as a result of acute oral exposure, and cutaneous contact may result in severe burns, ulceration, and scarring in people.
• Gastritis, chronic bronchitis, dermatitis, and photosensitization have all been linked to chronic (long-term) occupational exposure to hydrochloric acid in employees.
