Volume of mercury is given as 3.5 in³.
1 in³ = 16.387 cm³ = 16.387 cm³
So,
[tex] 3.5 in^{3} = 3.5\times 16.387 cm^{3} = 58.9 cm^{3} [/tex]
As density is defined as mass divided by volume.
Density of mercury is 13.6 g cm⁻³ .
That means
1 cm³ of mercury contains 13.6 g
58.9 cm³ of mercury contains 13.6×58.9 g
=798.4 g of mercury
Mass of mercury in 3.5 in³ of mercury is 798.4 g.
