A 5.00L balloon filled with 1.00 moles of O2 gas contains a total of how many liters?

Answers

Answer 1

Answer: To solve this we assume that the gas inside the balloon is an ideal gas and at STP. At standard temperature and pressure, it has been known that for 1 mol of a gas, the volume of this gas would be 22.4L. Therefore, the volume of O2 gas in the balloon would most likely be 22.4L.

How many moles in 28 grams of CO2

Answers

In the given question, in 28 grams of $\rm CO_2$ molecule 0.636 moles are present.

A mole is the amount of a substance which comprises exactly $6.022* 10^(23)$ 'elementary entities' of that substance.

To find the number of moles in 28 grams of $\rm CO_2$ , we first need to determine the molar mass of $\rm CO_2$ .

Molar mass of $\rm CO_2$ = 12.01 g/mol (carbon) + 2(16.00 g/mol) (oxygen)

= 44.01 g/mol

Now that we know the molar mass of $\rm CO_2$ , we can use the following formula to calculate the number of moles:

$\rm Number \ of\ moles = \frac {mass \ of \ sample\ (in \ grams) }{ molar\ mass}$

$\rm Number\ of\ moles = \frac {28 \ g }{44.01\ g/mol }$

= 0.636 mol

Therefore, there are 0.636 moles in 28 grams of $\rm CO_2$ .

Order of increasing atomic mass!

hope this helps :)

The first table, created by Mendeleev, was arranged by increasing atomic mass. However, it was later changed by Mosley, who arranged it the way it is today. He organized it by atomic number.

If people have trouble digesting fats, they most likely have trouble with __________.a. the esophagus and liver
b. the pancreas and stomach
c. the liver and gallbladder
d. the small intestine and large intestine

Answers

The correct answer is C. The liver and gallbladder.

Explanation

The liver, is an organ of the digestive system, is the most voluminous in the human body, and performs three vital functions essential for the organism: Detoxification in which it acts as a filter that collects and eliminates numerous toxins; the liver metabolizes carbohydrates, fats, lipids and proteins, secreting bile, an essential element for our digestion. Also, it prevents bleeding through a coagulation process; finally, works as a container for vitamins and glycogen, carbohydrates, and energy is stored in the form of sugar. On the other hand, the gallbladder is an organ of the digestive system, whose function is to store and concentrate the bile secreted by the liver required by the digestion process. The gallbladder stores bile until a stimulus caused by food intake, especially meat or fat. According to the above, if the functions of these two organs are impaired, the most likely is that the person will have trouble digesting fats. So, the correct answer is C. The liver and gallbladder.
