To determine the mass of 100 milliliters of trimethyl citrate, you need to know its density. The density of trimethyl citrate is approximately 1.15 g/mL.
Using the formula:
\[
\text{Mass} = \text{Volume} \times \text{Density}
\]
You can calculate the mass:
\[
\text{Mass} = 100 \, \text{mL} \times 1.15 \, \text{g/mL} = 115 \, \text{g}
\]
So, the mass of 100 milliliters of trimethyl citrate is approximately 115 grams.
