Question

Calculate the volume occupied by 4.25g of CO2 at s.t.p

Answer 1

it's occupy 2.16 L .

Answer 2

Moradi thanks for the answer but how did you work it out?

Answer 3

Any gas at STP occupies 22.4 L.
Molar mass of CO2 = 44 g/mol

No of moles of CO2 in 4.25 g = 4.25/44=0.096 moles

So volume occupied = 22.4*0.096=2.16 L

Answer 4

Got it ?

Answer 5

thanks abhisar.

Answer 7

I see where I made the mistake. I was multiplying 22.4 by 0.966 instead of 0.096. Got it . Thanks once again.

Answer 8

Anytime :)

Answer 9

STEP 1: Find the number of moles of CO2
\[Number of moles of CO _{2} =\frac{ mass }{ molar mass}\] \[= \frac{ 4.25g }{ 44g/mole}\] =0.0966
\[volume of CO _{2} = molar volume x moles = 22.4dm ^{3} \times 0.0966 =2.16dm ^{3}\]
