1.12cc=0.00112 liters

moles of gas = volume in liters ÷ volume at stp

moles of gas =0.00112÷22.4

moles of gas = 0.00005

NOW MOLES = NUMBER OF MOLECULES ÷ AVAGADRO NUMBER

NUMBER OF MOLECULES = MOLES × AVAGADRO NUMBER

NUMBER OF MOLECULES = 0.00005×6.023×10^23

NUMBER OF MOLECULES =0.00030115 ×10^23 = 3.0115×10^19
