The mass of an oxygen molecule is 5, point, 3, 1, times, 10, to the power minus 235.31×10 −23 grams. The mass of a proton is 1, point, 6, 7, times, 10, to the power minus 241.67×10 −24 grams. How many times greater is the mass of an oxygen molecule than the mass of a proton? Write your answer in standard notation, rounding to the nearest tenth.
