Question

89.6/ of CO, gas is filled in a cylinder at STP.

a) Calculate the mass of CO2 present in it. (Atomic mass C=12 0=16)

b) Calculate the no. of CO2, molecules present in the cylinder.​

Answer 1

Answer:

a) 176g

b) 4 moles

Explanation:

At stp 22.4L is 1 mole of substance

Then, 89.6L = 89.6/22.4 = 4 moles

So, mass of 4 mole of CO2 = 4×44 = 176g
