Answer:
1.0 × 10⁻⁵ mol/L
Explanation:
The concentration of a gas (C) in a liquid depends on its partial pressure (P), as expressed in Henry's law.
C = k × P
where,
k is the henry's law constant
When the partial pressure of the gas equilibrates at 3.0 × 10⁻⁴ atm, its concentration in the liquid is:
C = k × P
C = 3.4 × 10⁻² mol/L.atm × 3.0 × 10⁻⁴ atm
C = 1.0 × 10⁻⁵ mol/L
Answer: Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element's nucleus. It is the average weight of an element. It is the total number of nucleons in the atom's nucleus.
Assuming there were errors in atomic masses, Mendeleev placed certain elements not in order of increasing atomic mass so that they could fit into the proper groups (similar elements have similar properties) of his periodic table.

Answer:
223 g
Explanation:
Molar mass Fe = 55.845 g/mol
mass=molar mass* number of moles=55.845*4.00≈223 g
Answer:
A-) 8 Atoms
B-) 6 Atoms
C-) 16 Atoms
D-) 24 Atoms
Explanation:
A) Na (1 Atom) C2 (2 Atoms) H (1 Atom)O4 (4 Atoms)
1 + 2 + 1 + 4 = <em>8 Atoms</em>
B) H (1 Atom) 2F( 2 Atoms) 2B (2 Atoms) Li (1 Atom)
1 + 2 + 2 + 1 = <em>6 Atoms</em>
C) 2 He2 (2 Atoms) P (1 Atom) S1 (Atom) O4 (4 Atoms)
2 . ( 2 + 1 + 1 + 4 ) = 2 . 8 = <em>16 Atoms</em>
D) 3 He2 (2 Atoms) O4 (4 Atoms) P (1 Atom) H (1 Atom)
3 . (2 + 4 + 1 + 1 ) = 3 . 8 = <em>24 Atoms</em>
