The planet Mars has two moons – Phobos and Deimos. Phobos has a mass of 10.8 × 1015 kilograms, and Deimos has a mass of 2.0 × 10
15 kilograms. How much greater is the mass of Phobos than the mass of Deimos? A) 8.8 × 1015 kilograms
B) 8.8 × 1016 kilograms
C) 9.2 × 1014 kilograms
D) 9.2 × 1015 kilograms
Since the difference in their masses is 10,800,000,000,000,000 - 2,000,000,000,000,000 = 8,800,000,000,000,000 kilograms, the mass of Phobos is 8.8 × 1015 kilograms more than the mass of Deimos.
you need to convert pounds to kilograms. 196 pounds is 88.904 kilograms. The directions tell you that 20 milligrams of the drug is to be administered for each kilogram of a person's weight. Now you need to multiply 88.904 by 20. That should give you 1778.08 milligrams of lincomycin. You would then mix 250 cc's of saline solution to the 1778.08 milligrams of lincomycin; but I think its just asking you how much lincomycin to administer.
at what rate per minute should the 250 cc solution be adminstered
