Question

Find no. Of oxygen particles in 44g of CO2

Answer 1

Number of oxygen particles = 12.04 X 10²³

Explanation:

Given

mass = 44 g

no. Of oxygen particles = ??

Solution

No. of Moles =  mass in grams/ Atomic mass

No. of Moles =  44 / 44

No. of Moles =  1 mole

1 mole of CO2 contains 1mole of C and 2 mole of O

Number of particles = No. of Moles  X Avogadro's number

Number of particles = 2 X 6.022 X 10²³

Number of particles = 12.04 X 10²³
