Review the mass and size of an atom. A typical hydrogen atom, for example, has a mass of 1.66 x 10-24 g. Imagine how big a number we would need to describe the number of atoms in a real-life sample of an element. Could we somehow measure or handle a dozen or a ream of atoms? Explain.

so what is the problem with your lab report and whats the subject of the lab report? i will you

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.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
