Remdesivir is a broad-spectrum antiviral medication that is currently being used to treat Covid- 19. Remdesivir has this chemical formula: C27H35N6O:P. 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.

High-density lipoprotein (HDL) cholesterol is the good cholesterol because adequate levels reduce the risk of heart disease and stroke. HDL levels between 40. and 59 mg/dL are typical for a healthy individual. What is this range of HDL cholesterol in units of mol/L? The formula for cholesterol is C27H46O.
If you had a mole of U.S. dollar bills and equally distributed the money to all of the people of the world, how rich would every person be? Assume a world population of 7 billion.
3.68 Magnesium is lighter than other structural metals, so it is increasingly important in the design of more efficient vehicles. Mg2+ ions are present in seawater, and the metal is often prepared by "harvesting" these ions and converting them to Mg metal. The average magnesium content of the oceans is about 1270 g Mg2+ per ton of seawater, and the density of seawater is about 1.03 g/mL. What is the molarity of Mg2+ ions in seawater? The design for a concept car calls for 103 kg of magnesium per vehicle. How many gallons of seawater would be required to supply enough magnesium to build one of these ears?
3.107 As computer processor speeds increase, it is necessary for engineers to increase the number of circuit elements packed into a given area. Individual circuit elements are often connected using very small copper “wires” deposited directly onto the surface of the chip. In some processors, these copper interconnects are about 22 nm wide. How many copper atoms would be in a 1-mm length of such an interconnect, assuming a square cross section? (The density of copper is 8.96 g/cm3.)
4. Two engineers are serving as trainees in a laboratory of a pharmaceutical company. One of their tasks involves determining the identity of a vitamin they were given by using any equipment or method at their disposal. As a hint, their supervisor gave them a list of possible candidates for the vitamins identity which includes: Vitamin Molecular Formula Folinic Acid C20 H23 N707 C3H11NO3 C,H,N20 C17H20N406 Pyridoxine Niacinamide Riboflavin To identify the vitamins identity, the two trainees separated their sample into two equal portions and performed two separate tests: [a.] Engr. Mayo used the flame atomic absorption spectrophotometer in order to identify the elemental composition of the sample which happens to be 59.0% C, 5.0% H and 22.9% N by mass [b.] Engr. Busog on the other hand mixed his 3.88 g sample with 30.0 mL of nitrobenzene, C,H5NO2 (Latent Heat of Fusion = 79.81 J/g). Using Beckmann's method, he determined the freezing point depression to be 7.1 deg C. Based on the tests…
