Solubility is a property referring to the ability for a given substance to dissolve in a solvent
Answer: yes it it balanced you have 2 atoms on both sides of the equation
Explanation:
Atomic mass = number of protons + number of neutrons
= 10 + 8 = 18
In short, Your Answer would be Option C
Hope this helps!
Answer:
98.78 g/mol.
Explanation:
<em>Thomas Graham</em><em> found that, at a constant temperature and pressure the rates of effusion of various gases are inversely proportional to the square root of their masses.</em>
∨ ∝ 1/√M,
where, ∨ is the rate of effusion and M is the atomic or molecular weight of the gas particles.
- For two different gases, unknown gas (1) and hydrogen (2):
∨₁/∨₂ = √M₂/√M₁.
∨₁/∨₂ = 1/7,
M₁ = ??? g/mol, M₂ = 2.01588 g/mol.
∴ (1/7) = (√2.01588)/(√M₁)
By squaring both sides:
∴ (1/7)² = 2/(M₁) = 0.02
∴ M₁ = 2.01588/0.02 = 98.778 g/mol ≅ 98.78 g/mol.
