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

the correct answer is a
