Answer:
Explanation:
Hello,
In this case, since the rate equation turns out as shown below due to the first-order kinetics:
Its integration results:
However, the rate constant is computed by considering the given half-life time as follows:
In such a way, the required time in minutes to diminish the concentration by 66.8% of the initial turns out:
Best regards.

Explanation:
How the refractive index of the hexane + toluene mixture varies linearly with mole fraction, it means that the mole fraction is the fraction that each pure index contribute for the mixture index, so, calling <em>xh</em> the mole fraction of hexane and <em>xt</em> the mole fraction of toluene:
1.375xh + 1.497xt = 1.441
And, xh + xt = 1 (because there are only hexane and toluene in the mixture), so xt = 1- xh
1.375xh + 1.497(1-xh) = 1.441
1.375xh + 1.497 - 1.497xh = 1.441
-0.122xh = -0.056
xh = -0.056/(-0.122)
xh = 0.4590
