0.24529601530251 moles of neon
C because the volume of gas at 2.000 atm is 9.38L original volume was 3000l
Calculate the pressure using the Van der Waals equation and the pressure using the ideal gas equation PV=nRT. Subtract the two pressures to get the difference. then:<span>Calculate how many moles of ammonia you have using the ideal gas equation PV=nRT. Multiply the number of moles by the molar mass of ammonia to get the mass in grams.</span>

I think it's D cuz gasoline is technically a chemical so chemical energy. and the Engine which is working is mechanical or kinetic
so d. first from chemical to mechanical
hope i helped thnx
