Calculate the volume in milliliters (ml) of a 2.48 m
kohsolution required to titrate (neutralize) 25.0 ml of 6.52 m
hclsolution.

65.72 mL

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 = 6.52 M

V₁ = 25.0mL

M₂ = 2.48 M

V₂ = ?

Using the above formula , the volume of base , can be calculated as ,

M₁V₁ = M₂V₂

6.52 M  * 25.0mL  = 2.48 M * V₂

V₂ = 65.72 mL

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
