Which of the following is equal to the number of particles in 18 grams of carbon-12
mote1985 [20]

Answer:

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
