Molar mass=3*12+1.01*8+16*1=60.08g/mol
Mass Of The substance given=1g
No of moles of the substance=Mass given/Molar mass
=1/60.08=0.01664447
Each mole of a substance contains 6.022*1023 molecules of that substance.
So 0.01664447 moles contain 6.022*1023 * 0.01664447 molecules of that substance=1.00233*1022 molecules
Each molecule of C3H8O contains 3 atoms of carbon.
So 1.00233*1022 molecules contain 3*1.00233*1022
=3.00699*1022 atoms of Carbon.
Since it less than 2*1023 atoms the answer is option 1
