For the Shaefer-Fulton endospore stain method, the working solution of safranin is made by combining 10 mL of stock solution with 90 mL of distilled water. If you need to produce 1,046 mL of working solution, how many grams of safranin O will be required to make the smallest batch of stock solution possible? • Report your answer in grams using standard decimal notation rounded to two decimal places. • Include trailing zeros. • Do not include the units in your answer 。 If your answer is 100.105 g it would be reported as 100.11 。 If your answers was 100.203 g it would be reported as 100.20
