6) A sample of a sulfide of a metal M, (formula MxSy), is submitted to analysis to identify the metal. The sulfur in the sample is recovered as 120 mL of 0.250 M Na2S solution. The metal
in the same sample is recovered as 40.0 mL of 0.500 M solution of the metal ion.
a. Find the formula MxSy of this metal sulfide.
b. The molar mass of this sulfide is 150 g/mole. Identify the metal

The final answer for a is M2S3, for b is aluminum. Please show your work, thank you!
