Last updated: 7/9/2022

The molar mass of M(OH)2, formed by the hypothetical metal M, is 159.176 g/mol. What is the molar mass of the corresponding sulfide? Assume that the charge of the metal doesn't change. Provide your answer in decimal notation rounded to two decimal digits (i.e. to the hundredths place).
