How many atoms are in 2.50 moles of co2?
a. 4.52 x 1024 atoms
b. 1.52 x 1024 atoms
c. 5.02 x 1023 atoms
d. 3.01 x 1024 atoms
e. 7.53 x 1023 atoms?

Answer : The correct option is, (a)

Explanation :

As we know that,

1 mole of substance contains number of atoms.

As we are given that:

The moles of = 2.50 moles

Now we have to calculate the number of atoms present in molecule.

In , there are 3 atoms in molecule that means 1 atom of carbon and 2 atoms of oxygen.

As, 1 moles of contains number of atoms.

So, 2.50 moles of contains number of atoms.

Therefore, the number of atoms in 2.50 moles of are

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
