They told him that he was 30.8% too low in the boiling point he had just recorded. He had recorded a boiling point of 50 degrees C on his data sheet. what is the correct boiling point of the liquid he was working with in lab?

Explanation:

When you calculate percent it is important to determine the base value, because that is the denominator of your equation:

Here:

Subsitute and compute:

         ← answer

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
