1. (20 points) Calculate a suitable batch composition to give 1 kg of 11 Na20-9CaO 2MgO-2B03-75.5S102:0.550, (wt%) glass. Use sand (SiO2), soda ash (Na2CO3). Na2SO4, dolomite (CaCO3 MgCO3), limestone (CaCO3), and borax (Na-O-2B-03-10H0) as starting materials. Assume that 100% of the water, 75% of the S. 5% B03, and 2% Na0 from the batch are lost during the melting. (Note: Upload your solutions in Excel format only.)
