A certain medication recommends that each day a person be given 8 mg for every 100 lbs of weight. If 10,000 people take this med

ication each day and their average weight is 180 lbs, how many kilograms of this drug are used daily?

Answer:

Total Mass of daily drug used = 144 Kg

Explanation:

Total weight of the individuals =

180lbs * 10000 = 1.8 * 10^6 lbs

Since the drug is to be given 8 mg for every 100 lbs;

number of 8 mg doses = 1.8 * 10^6 / 100 = 1.8 * 10^4 doses

Total mass of the doses = 1.8 * 10^4 * 8 mg = 1.44 * 10^5 mg.

We divide the value above by 1000 to convert to Kg.

Therefore, total daily mass of drug used = (1.44 * 10^5)/1000 = 144 Kg

which sample, when dissolved in 1.0 liter of water, produces a solution with the highest boiling point?
andrew-mc [135]
<span>The correct answer is (C) 0.2 mole MgCl2.

according to Van't Hoff factor rule which is the ratio between the actual

concentration of the particles produced when the substance dissolved and

the concentration of the substance as measured from its mass, so here 0.2

mole MgCl2 is the higher van't Hoff factor as it has more ions than other

choices and the higher concentration.

and when the boiling point formula is delta Tb = Kb * m * i.

 when delta Tb is the change in boiling point.

 and Kb is molal boiling point constant

and m is the molality of the solution

and i is Van't Hoff factor.

 so we can see the relationship between i and delta Tb, the greater Van't Hoff factor the higher the boiling point. so 0.2 MgCl2 is the higher boiling point as it is the greater van't Hoff factor.</span>

Andre45 [30]

A converging lens made from a transparent plastic bottle filled with water is used to enable Pak Dollah read the newspaper.

<h3>What is long-sightedness?</h3>

Long-sightedness is an eye effect in which objects are not able to focus on the retina but behind the retina, therefore, near objects are not clearly seen except they are placed far away.

To correct long-sightedness, a suitable converging lens is used to bring the image to focus on the retina.

To construct a converging lens for Pak Dollah, the transparent plastic bottle is filled with water to serve as a converging lens and Pal Dollah will read through it.

Therefore, a converging lens made from a transparent plastic bottle filled with water is used to enable Pak Dollah read the newspaper.

What is the function of the digestive system? why is it important to the body?
tangare [24]

The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.

The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

Digestion is important because your body needs nutrients from food and drink to work properly and stay healthy. Proteins, fats, carbohydrates, vitamins NIH external link, minerals NIH external link, and water are nutrients. Your digestive system breaks nutrients into parts small enough for your body to absorb and use for energy, growth, and cell repair.

  • Proteins break into amino acids
  • Fats break into fatty acids and glycerol
  • Carbohydrates break into simple sugars

Each part of your digestive system helps to move food and liquid through your GI tract, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool. Nerves and hormones help control the digestive process.

what are most of the needed formulas to find the molar volume and the molar concentration (Cm) 11th grade chemistry​
stealth61 [152]

Answer:

Explanation:

molar volume=moles*given volume

for molar concentration we use two formulas molarity and molality

molarity=no of moles/volume

molality=no of moles/kilogram
