What volume does 1.5 x 10^24 molecules of co2 occupy at stp?

The volume occupied by given molecules of carbon dioxide at STP is 55.86 L.

Explanation:

Where:

N = Number of particles / atoms/ molecules

n = Number of moles

= Avogadro's number

We have:

N =

n =?

n = 2.4909 moles

Using ideal gas equation:

PV = nRT

where,

P = Pressure of carbon dioxide gas =  (at STP)

V = Volume of carbon dioxide gas = ?

n = number of moles of carbon dioxide gas =2.4909 mol

R = Gas constant = 0.0821 L.atm/mol.K

T = Temperature of carbon dioxide gas = 273.15 K  (at STP)

Putting values in above equation, we get:

V = 55.86 L

The volume occupied by given molecules of carbon dioxide at STP is 55.86 L.

there are two significant figures.
