QUESTION

# The simplest formula for butane is C2H5 and its molecular mass is about 60. What is the molecular formula of butane?

C_4H_10

Find the M_r of the compound's simplest formula a.k.a the empirical formula C_2H_5

(12.01 x 2) + (1.01 x 5) = 29.07g/mol

The M_r of the molecular formula is 60g/mol, therefore we have to divide 60 by 29.07.

60/29.07 = 2 (integer)

Multiply the entire empirical formula of butane by 2 to find the molecular formula.

C_2H_5 -> C_4H_10
