Question

grams of 1.0ft³ of Hg

Answer 1

Density of mercury $=$ $13.6g{cm}^{-3}$

Density of mercury in $g{ft}^{-3}=\dfrac{13.6}{(0.0328)^3}$ $=3.86\times10^5g{ft}^{-3}$

Now

Density($g{ft}^{-3}$ )$=\dfrac{mass(gm)}{volume({ft}^{3})}$

$3.86\times10^5=\dfrac{mass(gm)}{1}$

So mass in grams of $1.0ft^3$ of Hg is $3.86\times10^5$ gm
