(a) 0.0334 mol C, 0.1000 mol H and 0.0167 mol O

C = "\\dfrac{0.0334}{0.1000}=0.334"

H = "\\dfrac{0.1000}{0.1000}=1"

O = "\\dfrac{0.0167}{0.1000}=0.167"

Multiplying by suitable integer 6

"C=0.334\\times6=2.004\\approx2"

"H=1\\times6=6"

"O=0.167\\times6=1.002\\approx1"

Empirical Formula "=C_2H_6O"
