What is the density of carbon dioxide, co2, at stp?

d= 0.002 g/cm³

Explanation:

Data given:

Density of CO₂ at STP = ?

Solution:

So for density we have to know volume and mass of CO₂

For this

First we will find molar mass of carbon dioxide (CO₂)

Molar mass of CO₂ = 12 + 2(16)

Molar mass of CO₂ = 12 + 32 = 44 g/mol

CO

Now

we know that at STP molar mass of Carbon dioxide (CO₂) occupy 22.4 dm³/ mole of volume

22.4 dm³ = 22.4 L = 22400 cm³

Now to find the density of carbon dioxide (CO₂) at STP

mass of CO₂ = 44 g

Volume of CO₂ =  22400 cm³

                   d= m/v

Put values in above formula

                d= 44 g / 22400 cm³

                d= 0.002 g/cm³
