150 g SO₂ = 2.36 mol SO₂
M_r = 32.06 + 2×16.00 = 32.07 + 32.00 = 64.06
Moles of SO₂ = 151 g SO₂ × [1 mol SO₂/64.06 g SO₂] = 2.36 mol SO₂
I think it would be answer B or D . I gave you two answer because I dont want to be wrong with one

Answer:
C10H14N2
Explanation:
I don't believe one can deduce the molecular formula from just it's molar mass. There are too many possible combinations of elements that could add to the same mass. This is the correct formula for nicotine, taken from known information, not from an analysis of the molar mass alone. One can confirm the molar mass is in the correct range:
C10: 10*12 = 120
H14: 14*1 = 14
N2: 2*14 = <u> 28</u>
Total = 162 which is 160±5g/mol
