Answer:
0.30 M
Explanation:
In case of titration , the following formula can be used -
M₁V₁ = M₂V₂
where ,
M₁ = concentration of acid ,
V₁ = volume of acid ,
M₂ = concentration of base,
V₂ = volume of base .
from , the question ,
M₁ = ? M
V₁ = 25.0 mL
M₂ = 0.117 M
V₂ = 65.5 mL
Using the above formula , the molarity of acid , can be calculated as ,
M₁V₁ = M₂V₂
Putting the respective values -
M₁ * 25.0mL = 0.117 M * 65.5 mL
M₁ = 0.30 M

A sample of oxygen gas occupies a volume of 250 mL at 740 torr pressure. ... the gas exert if the volume was decreased to 2.00 liters? ... A 175 mL sample of neon had its pressure changed from 75.0 kPa to 150 kPa.
Explanation:
The answer is d. isotopes. The same element must have the same protons. And the atoms with same protons and different neutrons are called isotopes.
