A mixture of LİHCO3 and sand weighing 9.20 g is heated. After cooling, the residue composed of Li¿CO3 and sand weighs 6.80 g. Assuming that the sand in the sample is unaf- fected by the heat, calculate the mass loss due to the escape of gaseous CO2 and H2O. Calculate the mass of LIHCO3 in the original mixture. Calculate the mass of sand in the mixture. Calculate the mass percent of LIHCO3 in the mixture. What must be the mass percent of sand in the mixture?
