Question

Convert 1.75 × 1024 atoms of carbon to moles of carbon.

Answer 1

Number of C atoms = moles of C atoms x 6.02x 10^23. Therefore moles of C atoms = 1.75x10^24 / 6.02x 10^23 = 2.90 moles

Answer 2

Answer: The number of moles of carbon is 2.90 mol.

Step-by-step explanation:

We are given:

Number of atoms of carbon =
`1.75* 10^(24)`

According to mole concept:

`6.022\time 10^(23)` number of atoms are contained in 1 mole of an element.

So,
`1.75* 10^(24)` number of atoms will be contained in =
`(1)/(6.022* 10^(23))* 1.75* 10^(24)=2.90mol` of carbon.

Hence, the number of moles of carbon is 2.90 mol.
