A very poisonous diatomic gas used in world war II, is an early example of chemical warfare. At standard temperature and pressure a sample of this gas occupies a volume of 11.3 dm' and
weighs 35.5g. Calculate the molar mass of this gas. Identify the gas. (Round off your answers to
2 decimal places)

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

the answer is c i took the test

answer: option (a) is the correct answer.

explanation:

the measurement of hydrogen ions in a solution is known as ph.

if ph of a solution is less than 7 then the solution is acidic. if ph of a solution is greater than 7 then the solution is basic.

when the ph of a solution equals 7, then the solution is considered as neutral.

the ph of pure water is 7, therefore, it means that concentration of hydronium ions equals that of hydroxide ions.
