When a 8.000 g of mineral ore sample containing Sn(CO3)2 (238.7 g/mol) and other inert material was reacted with excess HCl solution and the liberated CO2 was bubbled through an excess solution of Ca(OH)2 (74.0 g/mol); the mass of precipitated CACO3 (100.0 g/mol) was 0.8900 g. The percentage Sn(CO3)2 in sample is? 1. 054.97 % 2. 026.56 % 3. 013.28 % 4. 08.35 %
