Question

find the amount by which 92 v/v alcohol is over proof (OP)




151°
161°
51°
61°​

Answer 1

Answer:

Explanation:

51 because

Answer 2

Given,

Concentration of alcohol = 92%$\frac{v}{v}$

To find,

The over proof percentage of the given alcohol sample.

Solution,

Proof spirit contains 57.1% V/V alcohol.

That is 57.1% V/V = 100

Then 92% V/V = ?

⇒$92$×$\frac{100}{57.1}$

=161

Over proof = 161-100

⇒61°

Henceforth, the given alcohol solution is 61° overproof.
