Please show how the gm-mole and weights were obtained. The finals answers are already provided, just show how they were calculated.

A dry copper concentrate composed of Cus, FeS and FeS2 is charged to a flash smelting furnace along with silica flux and dry air. The products are liquid matte (CuzS, FeS) at 72% Cu, liquid Fe2SiO4 and a gas composed of SO2 and N2. Please provide the solution on how the answers to the material balance table below were obtained: PLEASE show how the gm-mole per component was obtained (an expert just copied the gm-mole below and used it to calculate for the weight) Material Balance Table : Flash Smelting of Cu Basis = 1 gm - mole Cu Input Weight, & gm-mole Output Weight, ggm-mole Matte Concentrate Cus Fes FeS2 95.61 87.92 12 1 1 0.1 Cu2s Fes 79.58 8.79 0.5 0.1 Flux Slag SIO2 30.05 0.5 FE25i04 101.9 0.5 Air Gas 02 67.62 221.28 2.1 7.9 SO2 N2 102.51 221.28 1.6 7.9 N2 Total 514.05 Total 514.06
