Question 7 (5 points) (05.01 LC)
One mole of zinc has a mass of 65.4 grams. Approximately how many atoms of zinc are present in one mole of zinc?

6.02 x 10²³ atoms

Explanation:

The number of moles present in 1 mole of zinc will be 6.02 x 10²³ atoms. This is because a mole of any substance contains the Avogadro's number of particles which is 6.02 x 10²³ atoms.

A mole is simple a convenient way of estimating the number particles within a substance.

So every 1 mole of  a substance contains the same number atom in there.

For the give zinc, since it is 1 mole, it will contain 6.02 x 10²³ atoms

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.
