(b) Size and volume of the small test is 75 mm or 3 ml

2. Stand about a foot or two away from whatever you are smelling and waft the odor toward you with your hand.

3. Change of color, Production of a gas, Production of a solid precipitate, Change in temperature

4. just divide the volume by the number of drops.
