The answer is <span>The mass of sodium chloride formed is less than 76 grams.
</span>
Remember Mass is never gained or loss in any chemical reactions
So,
hydrochloric acid + sodium hydroxide => <span>sodium chloride + water
Total 76 gram Total will also 76 gram
In this case, the mass of sodium chloride will be less than 76 gram because we need to take out the mass of the water.

I am pretty sure that the statement which is true is A. a molecule having a covalent bond can be ionic. I choose this option because you usually ca see how electons of polyatomic ions are being covalenr and gain or loose ionic electrons in order to accomplish the octet.<span>

This problem is about conversion and dimensional analysis. Important information to know:
1 atm = 760 torr = 101.325 kPa
For atm to torr conversion:
0.875 atm * (760 torr / 1 atm) = 665 torr
For atm to kPa conversion:
0.875 atm * (101.325 kPa / atm) = 88.7 kPa
Thus the answer is b) 665 torr and 88.7 kPa
