Answer
The molar mass for $C_3H_6O_3$ is equal to 90.08 g.
Work Step by Step
1. Find the molar mass for each element in this compound:
$C: 12.01g$
$H: 1.008g$
$O: 16.00g$
2. Multiply each one of them by their respective subscript number:
$C: 12.01g * 3= 36.03g $
$H: 1.008g * 6= 6.048g $
$O: 16.00g * 3= 48.00g$
3. Calculate the total sum of these values:
$36.03g + 6.048g + 48.00g = 90.08g$
