I have the work if you need it: V= 17.0 L
The highlighted atoms have sp2 - sp3 hybridization. The highlighted atoms are carbon and nitrogen as shown.
The structure of Xanthine is shown in the image attached to this answer. The indicated atoms are Carbon and nitrogen as shown. Let us remember that hybridization has to do with the mixing of atomic orbitals to form appropriate hybrid orbitals that are suitable for overlap with orbitals of other atoms.
The highlighted carbon atom is sp2 hybridized because it has a carbon nitrogen double bond while the highlighted nitrogen atom is sp3 hybridized. Therefore, the highlighted atoms have sp2 - sp3 hybridization.

76.6 litres is the volume of the gas if pressure and temperature changes to STP.
Explanation:
Data given:
Volume of the gas V1 = 15.9 litres
pressure of the gas P1 = 589 kPa or 5.81 atm.
temperature T1 = 56.5 degrees or 329.3 K
Final pressure P2 = 101.3 kPa
Final temperature T2 = 273 K
At STP the pressure is 1 atm or 101.3 kPa and the temperature is 273 K. So from the question the final temperature and pressure is at STP.
from Gas Law:
=
V2 =
Putting the values in the above rearranged equation of Gas Law:
V2 =
= 76.6 Litres
Answer:
3. 0.36 L to the nearest hundredth
4. 542.40 L to the nearest hundredth
Explanation:
Question 3
Volume = 8.16 L
Number of moles = ?
At STP;
Temperature = 273 K
Pressure = 1 atm
Using the General gas equation;
PV = nRT where R = General gas constant = 0.0821
n = PV / RT
n = (1 * 8.16 ) / (0.0821 * 273)
n = 8.16 / 22.4133 = 0.3641 ≈ 0.36 to the nearest hundredth
Question 4
Volume = ?
Number of moles = 24.2 mol
At STP;
Temperature = 273 K
Pressure = 1 atm
Using the General gas equation;
PV = nRT where R = General gas constant = 0.0821
V = nRT / P
V = 24.2 * 0.0821 * 273 / 1
V = 542.402 L ≈ 542.40 to the nearest hundredth
