What mass of whole blood (in kg) can be contained in a plastic container whose dimensions are 125 mm by 110 mm by 35 mm? See cha

irakobra [83]

The mass of whole blood is 0.51 kg.

Given data:

The dimensions of container is 125 mmx 110 mm x 35 mm.

From the chart, the density of whole blood at 37 C is,

$\rho=\frac{1060kg}{m^3}$

The volume of container can be calculated as,

$\begin{gathered} V=125mm\times110mm\times35mm \\ V=481250mm^3\times\frac{1m^3}{10^{-9}mm^3} \\ V=4.8125\times10^{-4}m^3 \end{gathered}$

The mass of whole blood will be,

$\begin{gathered} \rho=\frac{m}{V} \\ \frac{1060kg}{m^3}=\frac{m}{4.8125\times10^{-4}m^3} \\ m=0.51kg \end{gathered}$

Thus, the mass of whole blood is 0.51 kg.
