A compound containing Ca, C, N and S was subjected to quantitative analysis and formula mass determination.A 0.25 g of this compound was mixed with Na_2CO_3, to convert all Ca into 0.16 g CaCO3A 0.115 g sample of compound was carried through a series of reactions until all its S was changed into SO_4^{2-}, and precipitated as 0.344 g of BasO4.A 0.712 g sample was processed to liberate all of its N asNH3 and 0.155 g NHwas obtained. The formula mass was found to be 156. Determine the empiricaland molecular formula of the compound:
