Methyl ethyl ketone (MEK) is a colorless liquid that has a sharp, sweet odor reminiscent of butterscotch and acetone. MEK has a chemical formula C4H8O. It is produced industrially on a large scale and is often used as an industrial solvent since it is soluble in water. Because it readily dissolves nitrocellulose, it was once a common ingredient in gun cleaning solvents.

Determine the molar mass of MEK. Blank 1 Carbon, Blank 2 Hydrogen, and Blank 3 Oxygen.

The air in one of the parts cleaning workshops was sampled and found to contain 153 ppm of MEK, what would this be in mg/m3?

Perform the conversion calculations (no decimal place), and include the unit of measurement, i.e., 62 mg/m3. Blank 4
