PLEASE HELP ASAP If an aluminum bar has a mass of 34.9 g and a density of 3.8 g/mL, what is the volume?

9.184mL

Explanation:

volume=mass/density

volume=34.9/3.8

volume=9.184mL

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.

catya your not at all which answer i've seen you do this on another question!
