How many atoms are in 1.3g C? Answer in Units of Atoms

Chemistry
1 answer:
Dima020 [189]3 years ago
3 0

Answer:Okay, so first, let's turn the grams into moles.

1.3 g C / 12.011 g/mol = 0.1082341187 mol C

Next, we need to multiply it by Avogadro's Number for the number of atoms.

0.1082341187 mol C * 6.022*10^23 mol^-1 = 6.51785863*10^22 atoms C

Now we take significant figures into consideration. We started with two, so we need to end it with two.

6.5*10^22 atoms C

On increasing which of the following factors, decreases the extent of physisorption? Surface area of the adsorbent Critical temp
Citrus2011 [14]

Answer: On increasing temperature at which adsorption is carried out decreases the extent of physisorption.

Explanation:

An adsorption where molecules of the adsorbate are placed or held on the surface of adsorbent by Vander waals forces is called physisorption.

There is basically physical bonding between the molecules of gas to the surface of a solid or liquid.

Physisorption is reversible in nature and occurs at low temperatures.

It is not specific in nature which means that all gases are adsorbed on the surface of every solid substance to some extent.

Thus, we can conclude that on increasing temperature at which adsorption is carried out decreases the extent of physisorption.

An adult mosquitoes lifespan is about 16 days how many minutes is that
AVprozaik [17]
The answer is 23, 040 minutes. To solve this you can start by changing days in to hours. We know that there are 24 hours in a day. To find how many hours are in 16 days you multiply 24 by 16 which is 384. Next you must find out how many minutes are in 384 hours. we know there are 60 minutes per hour. To find how many minutes are in 384 hours, you multiply 384 by 60. To this you get 23, 040 which is your answer.
