Remdesivir is a broad-spectrum antiviral medication that is currently being used to treat Covid- 19. Remdesivir has this chemical formula: C27H35N6O3P. Since it is made up of nonmetals, Remdesivir is a molecular compound. Answer the following questions about samples of Remdesivir. 1. On the first day of treatment, a patient receives 200. mg of Remdesivir intravenously. Compute the number of molecules of Remdesivir that are delivered in this dose to the patient.
