When mass=250 mg, V= 0.178 $cm^{3}$. When mass= 500 lb, V= $1.62\times10^{5}$ $cm^{3}$.

Work Step by Step

Density= $\frac{Mass}{Volume}$ Or Volume=$\frac{Mass}{Density}$. Given that, Density= 1.40 $g/cm^{3}$ When mass of the tablet is 250 mg, Volume= $\frac{250\times10^{-3}g}{1.40 g/cm^{3}}= 0.178 cm^{3}$. When mass of the tablet is 500 lb, Volume=$\frac{500 lb}{1.40g/cm^{3}}\times\frac{453.59g}{1 lb}=1.62\times10^{5}cm^{3}$
