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}](https://tex.z-dn.net/?f=%5Crho%3D%5Cfrac%7B1060kg%7D%7Bm%5E3%7D)
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}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20V%3D125mm%5Ctimes110mm%5Ctimes35mm%20%5C%5C%20V%3D481250mm%5E3%5Ctimes%5Cfrac%7B1m%5E3%7D%7B10%5E%7B-9%7Dmm%5E3%7D%20%5C%5C%20V%3D4.8125%5Ctimes10%5E%7B-4%7Dm%5E3%20%5Cend%7Bgathered%7D)
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}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Crho%3D%5Cfrac%7Bm%7D%7BV%7D%20%5C%5C%20%5Cfrac%7B1060kg%7D%7Bm%5E3%7D%3D%5Cfrac%7Bm%7D%7B4.8125%5Ctimes10%5E%7B-4%7Dm%5E3%7D%20%5C%5C%20m%3D0.51kg%20%5Cend%7Bgathered%7D)
Thus, the mass of whole blood is 0.51 kg.
the third answer is right.
<u>Answer
</u>
D. Salt water is denser than freshwater.
<u>Explanation</u>
A boat is able to float on water because it experiences an upthrust upwards.
The magnitude of the upthrust depends on the density of the liquid.
When the liquid is denser the boat will experience a great upthrust as compared to when in a less dense liquid.
If the boat sinks lower in the freshwater than in salty water, then Salt water is more dense than freshwater.
From reliable sources in the internet, the half-live of carbon-14 is given to be 5,730 years. In a span of 10,000 to 12,000 years, there are almost or little more than 2 half-lives. Thus, there should be
A(t) = A(0)(1/2)^t
where t is the number of half-lives, in this case 2. Thus, only about 1/4 of the original amount will be left.
