A Chemical Reaction, A(s) $\rarr$ B(s)+ C(g), Occurs When Substance a Is Strongly Heated

A chemical reaction, A(s) $\rarr$ B(s) + C(g) , occurs when substance A is strongly heated. The molecular mass of the gaseous product was to be determined from the following experimental data: Mass of A before reaction starts: 5.467 g
Mass of A after reaction finishes: 0 g Mass of residue (B) after cooling and weighing when no more gas was evolved: 4.762 g When all of the gas C evolved was collected and stored in an 875.0 mL glass vessel at 30.50 °C, the gas exerted a pressure of 346.0 torr.From this data, determine the apparent molecular mass of C assuming it behaves as an ideal gas.

A) 4.43 g mol ^-1
B) 0.0579 g mol ^-1
C) 17.27 g mol ^-1
D) 18.35 g mol ^-1
E) 44.01 g mol ^-1
