A sample of mixed carbonates, Li2CO3 (73.89 g/mol) and SrCO3 (147.63 g/mol), weighed 0.5310 grams. If this sample is titrated with acid, it is found that 20.10 mL, if this sample is titrated with acid, it is found that 20.10 mL of 0.5310 grams of 0.5010M HCl are required to reach the endpoint. Determine the percentage of SrO (103.62 g/mol) in the sample? Li2CO3 and SrCO3 are the only components in the sample.
