77.60 ml of .210 m naoh are required to neutralize 25.05 ml
ofh2so4 solution in a titrationexperiment.
calculate the molarity and normality of
theh2so4 solution.

Molarity =  0.650 M

Normality = 1.30 N

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 = 25.05mL

M₂ = 0.210 M

V₂ = 77.60 mL

Using the above formula , the molarity of acid , can be calculated as ,

M₁V₁ = M₂V₂

M₁ * 25.05mL =  0.210 M * 77.60 mL

M₁ = 0.650 M

Hence, the molarity of the acid = 0.650 M

Normality of a diprotic acid can be calculated by multiplying 2 with the value of molarity ,

Hence,

Normality = M * 2 = 0.650 * 2 = 1.30 N

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.
