Question

How many mL are 2.3 mol of CO2 at STP?

Answer 1

The volume of 2.3 moles CO2 is 51.5 L = 51500 mL

Step-by-step explanation:

Step 1: Data given

Number of moles CO2 = 2.3 moles

Step 2: Calculate volume CO2

p*V= n*R*T

⇒with p = the pressure = 1 atm

⇒with V = the volume = TO BE DETERMINED

⇒with n = the number of moles = 2.3 moles

⇒with R = the gas constant = 0.08206 L*atm/mol*K

⇒with T = the temperature = 273 K

V = (nRT)/p

V = (2.3*0.08206*273)/1

V = 51.5 L

The volume of 2.3 moles CO2 is 51.5 L = 51500 mL

Answer 2

0.052mL

Step-by-step explanation:

1mole of a gas occupy 22.4L.

Therefore, 1 mole of CO2 will also occupy 22.4L.

If 1mole of CO2 occupies 22.4L,

Then 2.3moles of CO2 will occupy = 2.3 x 22.4 = 51.52L

coverting this volume to mL, we simply divide by 1000 as shown below:

51.52/1000 = 0.05152mL = 0.052mL
