Ответ:
1.5 moles
Explanation:
Given data:
Mass of Carbon = 18 g
Number of particles = ?
Number of moles = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
For 18 g carbon:
18 g / 12 g/mol = number of moles
1.5 moles
1.5 × 6.022 × 10²³ particles
9.03 × 10²³ particles
