Answer is: 5,9.
Effusion is leakage of gas
through a small hole. Gases with a lower molecular mass effuse more speedy than gases with a higher molecular mass. R<span>elative rates of effusion is related to the molecular mass.
</span>M(O₂) = 32g/mol.
M(CO₂) = 44g/mol.
t₁ = 5s.
t₂ = ?
t₂/t₁ = √(M(CO₂)/M(O₂)).
t₂ = 1,17·5s = 5,9s.
Answer: The molarity of
is 0.07 M
Explanation:
According to the neutralization law,
where,
= basicity
= 1
= molarity of
solution = 0.1 M
= volume of
solution = 35 ml
= acidity of
= 2
= molarity of
solution = ?
= volume of
solution = 25 ml
Putting in the values we get:
Therefore, molarity of
is 0.07 M
