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: $36.03g + 6.048g + 48.00g = 90.08g$
