The more volatile the higher it goes on the graph. The less volatile the lower it
Goes.
It is true that at any given location, the physical properties of a substance do not change.
Answer:
132g/mol
Explanation:
The problem here is to find the molar mass of the compound in g/mol
To solve this problem, we simply sum the atomic masses of the atoms in the compound:
(NH₄)₂ SO₄:
Atomic mass of N = 14g
Atomic mass of H = 1g
Atomic mass of S = 32g
Atomic mass of O = 16g
So;
Molar mass = 2[(14 + 4(1))] + 32 + 4(16) = 132g/mol
It is essential for accurate results that the correct volume of blood is sampled to achieve a correct concentration (and dilution, if liquid heparin is used), and that blood and anticoagulant are well mixed immediately after sampling.
