Answer:
39.65L
Explanation:
First, let us calculate the number of mole present in 3.56x10^23 molecules of C3H8.
1 mole of any substance contains 6.02x10^23 molecules as discovered from Avogadro's hypothesis. This means that 1mole of C3H8 contains 6.02x10^23 molecules.
Now, if 1mole of C3H8 contains 6.02x10^23 molecules, then Xmol of C3H8 will contain 3.56x10^23 molecules i.e
Xmol of C3H8 = 3.56x10^23/6.02x10^23 = 0.59mole
The equation for the reaction is given below:
C3H8 + 5O2 —> 3CO2 + 4H2O
From the equation above,
1 mole of C3H8 produced 3moles of CO2.
Therefore, 0.59mole of C3H8 will produce = 0.59 x 3 = 1.77mole of CO2.
Now let us calculate the volume occupied by 1.77mole of CO2. This is illustrated below:
1 mole of any gas occupy 22.4L at stp.
Therefore, 1.77mole of CO2 will occupy = 1.77 x 22.4 = 39.65L
Therefore, 39.65L of CO2 are produced.
