Question

What is the mass of of 3.20 X 10^23 particles of Co2?​

Answer 1

Mass = 23.36 g

Step-by-step explanation:

Given data:

Number of particles of CO₂ = 3.20 ×10²³

Mass of CO₂ = ?

Solution:

1 mole contain 6.022×`10²³ particles,

3.20 ×10²³ particles × 1 mol / 6.022×`10²³ particles

0.531 mol

Mass of CO₂:

Mass = number of moles × molar mass

Molar mass = 44 g/mol

Mass = 0.531 mol× 44 g/mol

Mass = 23.36 g
