The empirical formula for a compound is ch2o and the molar mass is 180.2g mol which is molecular formula for this compound

                Molecular Formula  =  C₆H₁₂O₆

Solution:

Molecular formula is calculated by using following formula,

                     Molecular Formula  =  n × Empirical Formula  (1)

Also, n is given as,

                      n  =  Molecular Weight / Empirical Formula Weight

Molecular Weight  =  180.2 g.mol⁻¹

Empirical Formula Weight  =  12 (C) + 2 (H₂) + 16 (O)  =  30 g.mol⁻¹
Son
                      n  =  180.2 g.mol⁻¹ ÷ 30 g.mol⁻¹

                      n  =  6

Putting Empirical Formula and value of "n" in equation 1,

                     Molecular Formula  = 6 × CH₂O

                     Molecular Formula  =  C₆H₁₂O₆

It is 4.92 e-4 sorry if i am wrong
