Write the equality and two conversion factors, and identify the numbers as exact or give the number of significant figures for each of the following:a. The label on a bottle reads 10 mg of furosemide per 1 mL.b. The Daily Value (DV) for selenium is 70. mcg.c. An IV of normal saline solution has a flow rate of 85 mL per hour.d. One capsule of fish oil contains 360 mg of omega-3 fatty acids.
By using estimation techniques, determine which ofthe following is the heaviest and which is the lightest: a5-lb bag of potatoes, a 5-kg bag of sugar, or 1 gal of water(density = 1.0 g/mL).
An over-the-counter medication has 325 mg of its active ingredient per tablet. A lab has 0.5 kilograms of the active ingredient. Each bottle of medication has 48 tablets. How many full bottles of medication can the lab make?
Conversion factors:
(1000 mg = 1 g)
(1000 g = 1 kg)
(1 tablet = 325 mg)
(1 bottle = 48 tablets)
Group of answer choices
32 full bottles of medicine
1538 full bottles of medicine
0 full bottles of medicine
6770 full bottles of medicine
