How many moles are there in 8.50 x 10^24 molecules of sodium sulfate, na2so3?

(molecules to moles)

a.) 51.2 moles

b.) 5.12x10^48 moles

c.)14.1 moles

d.)1.40 moles

C) 14.1 moles

Explanation:

1 mole = 6.02 *10^ 23

8.50 * 10^24 molecules *(1 mole/6.02*10^23 molecules) ≈ 14.1 moles

that's what i got you can count the number of 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.
