Answer
The molar mass for $C_2H_4Cl_2$ is equal to 98.95 g.
Work Step by Step
1. Find the molar mass for each element in this compound:
$C: 12.01g$
$H: 1.008g$
$Cl: 35.45g$
2. Multiply each one of them by their respective subscript number. For the elements that are enclosed in brackets, also multiply them by the subscript of the brackets:
$C: 12.01g * 2= 24.02g $
$H: 1.008g * 4= 4.032g $
$Cl: 35.45g * 2= 70.90g$
3. Calculate the total sum of these values:
$24.02g + 4.032g + 70.90g = 98.95g$
