How many molecules are there in 31.8 moles of water? 1.91 x 1025 molecules
1.91 x 1022
5.28 x 10-23 molecules
5.28x 10.25

Explanation:

Given

31.8 moles of water

Required

Determine the number of molecule

In standard units: 1 molecule of water is:

Multiply both sides by 31.8

Express 191.4996 as a standard form

Apply law of indices:

Approximate:

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.

you gotta add the following molecules so we can give u an answer
