How many oxygen atoms are in 25 g of oxygen?

Chemistry
1 answer:
shutvik [7]3 years ago
8 0

Answer:

Explanation:

Carbon Dioxide-CO2

To get molecules, we must convert grams to moles and moles to atoms using Avogadro's number.

Molar mass of CO2=

C:12.0g+O:16.0gx2=44.0g CO2

25.0g CO2 | 1 mol CO2 | 6.02x10 23 molecules CO2

= 3.42x10 23 molecules CO2

1 | 44.0g CO2 | 1 mol CO2

Now to get the number of oxygen atoms.

Since there are 3 atoms in CO2 and 2 of them are oxygen, we will divide by 3 (1.14x10 23) and multiply by 2 (2.28 x10 23)

So the number of oxygen atoms in 25.0 grams of CO2 is 2.28x10 23 or 228 000 000 000 000 000 000 000

how is the arrangement of molecules in a dense object different than arrangement by molecule in a less dense object
solmaris [256]

Answer:

The molecules in a dense object are tightly packed together

Explanation:

This happens because the closer molecules are the denser the object is, however, if they get too close it can be a very disastrous result and the compound becomes very unstable. Hope I could help! :)

Where in an equation for photosynthesis does oxygen belong?
LUCKY_DIMON [66]

Answer:

on the right side, because it is a product

Explanation:

photosynthesis is the chemical reaction with the help of which plants produce chemical energy with the help of light energy.

_______________________________________________

The general standard for writing chemical reaction is that

  • The chemical which are input to the process of chemical reaction are written on left hand side . They are known as reactant.
  • The output of chemical reaction are written on right side. They are termed as product.
  • Transition of reactant to product is shown by arrow.

Chemical reaction for photosynthesis is given by below equation

6CO2 + 12H2O  + light ----------------> C6H12O6 + 6O2 + 6H2O  

We can see that 6 molecules of light combines with 12 molecules of water to give one molecule of glucose and 6 molecules of both water and oxygen.

As, oxygen is the output of photosynthesis process, it is written on the right-hand side of equation and is product of this reaction.

.

Thus, of the options given below for

In an equation for photosynthesis does oxygen belong

on the right side, because it is a product
