Question

12.8 cm³ of benzene is dissolved in 16.8 cm³ of xylene. Calculate % by volume of benzene (43.24)

Answer 1

Answer:

43.24℅

Explanation:

℅v/v= (volume of component×100/volume of solution)

= 12.8×100/12.8+16.8

= 12.8×100/29.6=43.24℅

Answer 2

Answer:

% volume of benzene is 43.24%.

Explanation:

We have given that the volume of benzene is  12.8 cm³.

Volume of xylene is 16.8 cm³.

So, the total volume of the solution = volume of benzene +volume of xylene.

                                                           = 12.8+16.8 = 29.6 cm³.

we know the formula

%$Volume\ of\ benzene = \dfrac{volume\ of\ benzene\times 100}{Total\ volume\ of\ the\ solution} = \frac{12.8\times100}{29.6} = 43.24$ %

So,% volume of benzene is 43.24%.
