A. CoH4
B. PSF3
C. SrS
D. ZrO2

The answer is (3). The number of Sr is the same so if the compound has the smallest gram formula mass, it has the highest percent composition by mass of strontium. So the answer is (3).

The study of chemical is called chemistry.

The correct answer to the question is option C that is C SrS.

What is molecular mass?

  • The molecular mass is the mass of a given molecule: it is measured in daltons.
  • Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.

The molecular mass of Sr is 87.62 and sulfur is 32 after joining these we will get 123.22.

Hence, the correct answer is option C.
