A sample of gas has a mass of 38.9 mg. Its volume is 228 mL at a temperature of 55 °C and a pressure of 831 torr. Find the molar mass of the gas. Express your answer in grams per mole to three significant figures.

-be a crystalline solid

- be soluble in water

-conduct electricity

hope this : )

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.
