Find which line in the following outlined problem contains a mistake. Explain how to correct the mistake, if there is one.

"Study the problem and proposed solution below. Is the final answer correct? Then click the No mistakes button. Is the final answer wrong? Then click the button in front of the line with the first mistake and correct the mistake."

Note: don't worry about correcting the rest of the solution, after the first mistake.

The density of a pure substance is its mass per unit volume. The density of
ethylene glycol has been measured to be l1097. .
g
Calculate the mass of 205. mL
of ethylene glycol.
Be sure your answer has a unit symbol and the correct number of significant
digits.
Solution:
m
Write down the definition of density.
