Answer:
in 6.0 E3 g of blood at a concentration of 0.62 ppm there are 3.5g of lead content
Explanation:
- blood density: 1.06 g/L
- ppm ≡ mg Pb / L blood
⇒ V blood = 6.0E3gblood * L / 1.06gblood = 5660.37 L blood
<u> mass of lead:</u>
⇒ 5660.37 L blood * 0.62 mg Pb / L blood * 0.001 g / mg
⇒ mass = 3.509 g of lead
Shape
A gas is shapeless all other things being equal. It will, if put in a container, occupy every part of the container.
A liquid could also be thought of shapeless. If put in a container, it need not occupy the entire container. It will occupy as much as its calculated volume will permit it to occupy.
A solid will only occupy its original shape.
Volume
A gas will occupy whatever container it is put in within limits. You cannot put a 72 mols of gas in a mm^3 container without some amazing ability to apply a lot of pressure.
A liquid will occupy a volume determined by its density and mass. In general liquids cannot be compressed.
Whatever volume a solid has to start with, it will retain that volume all other things being equal.
This is actually very hard to describe.
