B) A balloon having a volume of 10 L is placed on a sensitive balance which registers a weight of 2.833 g. What is the “true weight” of the balloon if the density of the air is 1.294 g. L^-1?

The mass of air displaced by the balloon exerts an upwards force of buoyancy
#"True weight"="Apparent weight" + "Force of buoyancy"#
#=(2.833 + 12.94) = 15.773\ g# .
