How much lift does the average latex helium filled party balloon produce?

How much lift does the average helium filled party balloon produce? (not including any extras like ribbon string)

That gives it a volume of $\frac43 \pi r^3$ so annoyingly mixing units, $\frac43 \pi {\,0.15\,\text{m}^3} = 0.014{\,\text{m}^3}$
Air has a density of 1.2 $\text{kg m}^3$ at room temperature and pressure and Helium $0.176 \,\text{kg m}^3$ So your balloon has a lifting capacity of $0.014 * (1.2-0.176) = 0.014\,\text{kg}$
