CREATE TABLE table_26211058_1 (calculated_activity___bq__ VARCHAR, specimen_weight_size VARCHAR)

If the specimen weight/size is 1000 g / 8.79 cm, what is the calculated activity?
SELECT COUNT(calculated_activity___bq__) FROM table_26211058_1 WHERE specimen_weight_size = "1000 g / 8.79 cm"
SELECT COUNT("calculated_activity___bq__") FROM "table_26211058_1" WHERE "1000 g / 8.79 cm" = "specimen_weight_size"
