What is the number of moles present in 2.1 x 10²⁴ atoms of C?
To find the number of moles present in a given number of atoms, you need to use Avogadro's number, which is defined as 6.022 x 10²³ atoms per mole. Here's how to calculate it:
1. Start with the given number of atoms: 2.1 x 10²⁴ atoms.
2. Divide the number of atoms by Avogadro's number to convert it to moles.
2.1 x 10²⁴ atoms / 6.022 x 10²³ atoms per mole = 3.49 moles (rounded to two decimal places).
Therefore, there are approximately 3.49 moles of carbon (C) present in 2.1 x 10²⁴ atoms of carbon.
