Iron has a density of 7.874 g/ml. if a sample of iron has a mass of 7.75 grams, what is the volume of this sample in dl

Given:

Density of iron:7.874g/mL

Mass of iron : 7.75 gms

Now we know that

Volume = Mass/density

Substituting the given values in the above formula we get

Volume of iron= 7.874/7.75= 1.016 mL

Volume of iron = 0.01016 dL

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.
