1. Find the molar mass of Carbon:
* The molar mass of Carbon (C) is 12.01 g/mol.
2. Convert grams to moles:
* Divide the given mass by the molar mass:
1.9 g / 12.01 g/mol = 0.158 mol
3. Use Avogadro's number:
* Avogadro's number states that there are 6.022 x 10^23 atoms in one mole of any substance.
* Multiply the number of moles by Avogadro's number:
0.158 mol * 6.022 x 10^23 atoms/mol = 9.51 x 10^22 atoms
Therefore, there are approximately 9.51 x 10^22 atoms in 1.9 g of Carbon.
