A student finds the density of a liquid using its mass and volume. The student includes the mass of the empty cylinder in the mass used in the calculation. The volume is measured correctly. Which change to the method corrects the result?
Subtract the empty cylinder mass; the calculated density decreases.
Subtract the empty cylinder mass; the calculated density increases.
Add the empty cylinder mass; the calculated density decreases.
Add the empty cylinder mass; the calculated density increases.
