What is the molecular formula of a molecule that has an em formula of CH and a molecular mass of 78.11 g/mol?
weight of CH is 12.01 + 1.0 = 13.01
78.11/13.01 = 6.004. Round to whole number of 6.00. So the molecular formula must be (CH)6 or C6H6.
78.11/13.01 = 6.004. Round to whole number of 6.00. So the molecular formula must be (CH)6 or C6H6.
